We do not know that, and neither do you. We live in a mystery in that regard. All we can do if we want to be truthful is admit we don't know what happens after death. We simply don't know. That's the truth. If you can't admit that to yourself, you are clinging to your notions the same way religious fundamentals cling to theirs. Its okay to have spiritual ideas, but none of us can honestly speak in certainties like that. You have no idea if reincarnation is true or false. To say you do is the type of arrogant/fearful clinging that keeps so many people from ever actually growing (I would say growing spiritually, but that is just my opinion based on the way I define spirituality). The idea is to live in wonder, not cling to fixed ideas about those things which are ultimately unknowable.

Try Modifinil or Adrafinil. Both promote wakefulness and help with productivity. For the memory, consider a nootropic, such as Piracetam, Noopept, or Oxiracetam.

"Right" is different as it applies to particular intentions. It is not an objective truth. The question is, what intentions does a person have for which the action he takes is right.
