A little tip I picked up from a film surrounding teenage troubles: When your self-esteem plummets (like when you face rejection, get badgered at work, feel humoungously fat etc) just do things that make you feel really good. Read a great book, go grocery shopping, sing, watch some good short films, sample a new restaurant etc. It really works!!!

One should try wearing one of those Superman ‘underoos’ that brian921 mentioned. … really work well when you have a bad day. Gauranteed to make you feel really good.
As for me I have a collection on ‘Shaktimaan’ briefs that I bank on. They give me wings….
Or you could go on vacation to Goa.
Guess “teenage” tricks apply well beyond.
