** The things-I-did-for-first-time for you to guess are:

PFF(ever):
http://www.bartleby.com/110/I3.html (MATTER) is more general than
  [Org.M.] is more general than [A.L.] is more general than [A.H.]
  is more general than [T] is more general than [F]

PPS(ever):
Cooking (assume 330.4 (prepare food)) -> Yes, but more specifically what?
Spaghetti - CORRECT ANSWER! Now what does PPS mean? (I deliberately used
obscure synonyms so you wouldn't guess it meant "Spaghetti".) PrPaSa?

GPG(20yrs): The thing to guess is part of "INTELLECT" or
  "VOLITION" or "AFFECTIONS", pick any one of those categories
  for more.
http://www.bartleby.com/110/I5.html (VOLITION) is more general
  than [Sup.O.] is more general than [C1] is more general than [C2]
  is more general than [G] (see below)
http://www.bartleby.com/110/I6.html or
  http://www.thesaurus.com/roget/VI/ (AFFECTIONS = Words
  Relating to the Sentient and Moral Powers) is more general
  than [Per.A.1] is more general than [P.P.] is more general
  than [A] is more general than [G] is more general than
  [B.T.G.] is more general than [P].
dance is a synonym of dancing triggers joy is a synonym of pleasure
  triggers [Fu.] is a synonym of [Pl] triggers [Ga] is more
  general than [P].
dance is a synonym of dancing is a kind of Pleasure and Pleasureableness
  is a kind of Personal Affections is a kind of AFFECTIONS.
Pleasure and Pleasureableness is a joint supercategory of both dance
  and Amusement (see below)
restaurant is a kind of eating.
eating is a kind of consumption is a synonym of use is a
  synonym of enjoyment is a kind of pleasure is a synonym of
  Diversion is more general than Amusement is a kind of Recreation
  is more general than Game is more general than Board/Table Games
  is more general than Pool.

Regarding how I got to that place where I did that activity:
http://www.bartleby.com/110/I2.html (SPACE) is more general than MOTION:
taking a walk, for pleasure -> No, too painful, impossible to enjoy walking.
taking a walk, to get somewhere -> Only a tiny part of getting there was
  walking, although that cost most of the pain. The thing you need to
  guess is what I did once I got there, not so much how I got there.
  Go back to INTELLECT or VOLITION or AFFECTIONS for those.
swim is a kind of go is more general than drive
swim is a kind of locomote is more general than drive
swim is a kind of move is more general than drive
You correctly guessed drive as my means of getting there.
swim (ambiguous, do you mean: fooling around in the water
  for recreation, which is a kind of AFFECTIONS, or swimming
  competetively such as in olympics, which is also a kind of
  AFFECTIONS, or swimming to get somewhere such as swimming to
  shore after a boat capsizes, which is a kind of MOTION in the
  general category SPACE?)
swim(AFFECTIONS) triggers [Fu.] is a synonym of [Pl.] triggers
  [Ga.] is more general than [B.T.G.] is more general than [B]
  triggers [P] which is what I did for first time in 20 years.

Swimming (275.56 (bathe)) -> Applies to two different things
I did which are not in my original list of three things to
guess because they aren't recent (past two months), but if
you want to guess such old news:

SLM(ever): Guess where 2000.Jun?
http://www.bartleby.com/110/I3.html (MATTER)
Note: After guessing the kind of activity (you already did),
  and the kind of place (current clues here), finally you must
  locate the specific place geographically in the world. I
  could instead have you locate the geography before the kind
  of place, but I intuit that would be harder for you (or
  anyone). Here's what Lexical FreeNet says about how to get
  from the general category MATTER to specifically the kind of
  place where I swam:
MATTER is more general than fluid is a synonym of liquid is
  more general than water.
water is a synonym of body of water is more general than lake
  which is the kind of place I swam.
water is a synonym of [Wa.S.] comprises [R] which is the kind
  of place I swam.
sea is a kind of body of water is more general than lake

SAP(19yrs): Guess where 2000.Sep/Oct? Should be listed under
  category MATTER just like the other, but is listed under
  AFFECTIONS instead.
http://www.bartleby.com/110/I6.html (AFFECTIONS) is more
  general than [Per.A.] is more general than [P.P.] is more
  general than [A] is more general than [] where I swam
  2000.Sep.
Update Friday night: I found a way to fake it under MATTER:
  MATTER is more general than fluid is a synonym of liquid
  is more general than water is a synonym of body of water
  is more general than lake is more general than [Pu.] is a
  synonym of [P2] which is located at [A] where I swam.

* Why am I including two more things I did recently?

WI2:
http://www.bartleby.com/110/I6.html (AFFECTIONS) is more general than 
  [Per.A.] is more general than [P] is in the same section as [P].


* What two new things did I do recently?

ING: I did what action to what thing?
Action: http://www.bartleby.com/110/I1.html (ABSTRACT RELATIONS) is more
  general than [Pow.] is more general than [P.O.] is more general than
  [P] is a synonym of [C] is more general than [C.M.] is more general than [I]
Thing: http://www.bartleby.com/110/I6.html (AFFECTIONS) is more general
  than [Per.A.] is more general than [P] is a synonym of [D]
  is more general than [A] is a kind of [D/R] is more general than [G]

WNP:I did what action to what thing?
Action: http://www.bartleby.com/110/I1.html (ABSTRACT RELATIONS)
  is more general than [Pow.] is more general
  than [P.O.] is more general than [P] is a synonym of [C]
  is more general than [C] is a synonym of [W]
Thing: http://www.bartleby.com/110/I5.html (VOLITION) is more general
  than [Aut/C] is more general than [D] is more general than [P]
  is more general than [F] is a kind of [P] is part of [P].


* Not close to anything I've done recently, so I can't 
attach this guess to any specific thing you were trying to guess,
but if you happen to get close to one of them, at that time
I'll move this guess up to be with the appropriate target:

Painting (Ambiguous, pick: 362.13 (color, like
  housepainting), or 901.8,9 (embellish, ornament), or 574.20
  (picture), or 572.6 (represent)?)
Housepainting. -> That isn't close to anything I've done recently
for the first time ever or in a long time, so you would do best to
drop this section and conentrate on the other sections (TAN
WSMS GPG SLM SAP where you are already making progress, or
PFF WI2 ING WNP where you haven't started but it should be
easy once you start).
