Spirit and soul is horseshit of the worst sort. Obviously there are no fairies, no Santa Clauses, no spirits. What there is, is human goals and purposes as noted by sane existentialists. But a lot of transcendentalists are utter screwballs.

People have motives and thoughts of which they are unaware.

Self-esteem is the greatest sickness known to man or woman because it's conditional.

I think it's unfair, but they have the right as fallible, screwed-up humans to be unfair; that's the human condition.

By not caring too much about what people think, I'm able to think for myself and propagate ideas which are very often unpopular. And I succeed.

Convince yourself that worrying about many situations will make them worse rather than improve them.

If human emotions largely result from thinking, then one may appreciably control one's feelings by controlling one's thoughts - or by changing the internalized sentences, or self-talk, with which one largely created the feeling in the first place.
