Where was this information when I was seven?

Shit

If you don't fight, you can't lose

Honestly good advice. Especially early in life. We lionize not quitting - sticking to it. But we don't really talk about why and when. Of course, building a habit of sticking to things that are important is a good habit to have. But what is important?

The reality is, we all have our own strengths and weaknesses, likes and dislikes. If you try your hand at, say, skateboarding, but find you are bad at it and don't like it - quit. Sell your skateboard. Go do something else with your time that is more enjoyable for you, that you have a better natural disposition for. Try a bunch of new things, until you find something that you really love doing! And if in a week or a month or a year or ten years, you find that you still can't shake the thought of skating from your mind, you can always try again.

Or just find a way to fight where you can win.

Strange game. The only winning move is not to play.

Funny but not true. Don't give up too early, don't give up too late. Give up at the right time. Anything else is a skill issue.

If at first you don't succeed... give up.

That is the dedication required to be a successful and low income loser.
