The best way to do Psionics is treat them just like spells, but put no limits on memorization. Instead there is a cumulative percentage chance with each casting (equal to the psionic ability's level) that your head explodes during the casting (and this chance resets to zero after a full night's sleep). So a 1st level psionic ablity would be a 1% chance, but if you cast another 1st level psionic ability or the same one, you then have a 2% chance. If you followed that up with an 8th level psionic ability you would have a 10% chance of your head exploding.
Nah.
