Philosophy on Dealing with Negativity: Practice for Fame and Fortune by Ignoring Negativity!

Think of negativity as a great, fun opportunity to ready yourself for a life of fame. Famous people have to ignore vast amounts of negativity about them. If they didn't, they would forever be wasting their time apologizing, defending theirselves, or crying foul to people in charge.

Do you find yourself getting worked up over one little comment? Think about it this way: Even if they wanted to, a famous person couldn't read all the bad things about them. They would have to hire an entire, full-time staff of a hundred people to read, get upset, and respond to all the stuff written about them. Start practicing now so when you get famous, you don't have to hire a hundred people to get upset for you.

The key is really to think of negativity as just "part of the game". Like Tetris, The Legend of Zelda, or PAC-MAN. You just step around it. Keep moving ahead. Don't look back at that thing you stepped around. Stop that. Stop lookihg back. Are you looking back? POW you lost the level because you were looking back. Did you learn? Stop looking back at "that thing" you stepped around.


About Me

Taught myself programming in 7th grade from my older brother's math book before I had a computer (1978). I would run the programs on paper to see what they would do. I learned to program for joy at the start of the personal computer revolution.

@JepeStigNielsen, I provided my own complete answer to this below. But rather late, so it still has a low vote. (Actually, I think it's the best answer!) Please feel free to comment below my answer. Thanks! –

Fixed typo.... Better to lead with the general solution and follow with "concrete examples". Switched their order. Formatting/copy-editing.
