$1+.10, 2TT, Stars. All-in on first hand?

[Poker Clif]

I know that basic stategy is to be tight, but. . . I'm a new player, starting at micro level with $50 bankroll, want to build it up and play at 3% level as I go, i.e, $3+.40 with $100 bank. Three straight 2TTs, two players went all-in on the first hand, and I called. I had AA, AA, and AK, and I busted out all three times to worse hands. Should I put that down to variance and keep going in when I have the goods? Or should I fold the best hand/nuts and let the maniacs fight it out?
