Unpleasantness

One thing that makes people really unpleasant is not earning a means of living or not earning enough.

Always limit the time to money as much as possible. Speed matters here.

Same goes for not enough money.

Don’t become tight fisted, life doesn’t work that way.

If you believe in reciprocity, Treat money like you have an abundance of it, put it to work immediately, buy things for others (esp, if there are women in your life - buy them small gifts often) and make donations. Every now and then buy stuff for tyourself.
