You are your own worst enemy

It’s easy to blame others.

It’s hard to blame yourself.

It’s easy to blame things out of your control.

It’s hard to blame those things that are within your control.

Rules can help you make better decisions. Your goal should be to follow your rules. Not making money. Making money should be a product of following your rules.

Don’t think of yourself as a gamblin’ man. Think of yourself as a risk manager.

Make smarter bets through time. Don’t trade too big in any one position or in any one day. When you place your bets is just as important as where you place your bets.
