a great list from stefan sagmeister's diary:
Complaining is silly. Either act or forget.
Thinking life will be better in the future is stupid. I have to live now.
Being not truthful works against me.
Helping other people helps me.
*Organizing a charity group is surprisingly easy.
Everything I do always comes back to me.
Drugs feel great in the beginning and become a drag later on.
Over time I get used to everything and start taking it for granted.
*Money does not make me happy.
Traveling alone is helpful for a new perspective on life.
Assuming is stifling.
Keeping a diary supports my personal development.
Trying to look good limits my life.
Worrying solves nothing.
Material luxuries are best enjoyed in small doses.
Having guts always works out for me.
*these are the only items on the list i'm at all dubious about, since i have no personal experience with them.
