1. Take a 30 minute walk every day regardless of weather.
2. Take three months off from video games. The first three weeks will suck. Remind yourself several times a day that this is for something possibly better.
3. Don't linger on your past mistakes beyond a reminder of where you don't want to be. Buildingg your character is a path filled with wrong turns and mistakes. The best we can do limit the effects of those mistakes based on our setup. ... Build character like you would in a rogue like if that's helpful
4. Develop emotional awareness and intelligence. That's a book and a skill.
5. Talk to people with the respect you want to receive.
6. Accept the parts of yourself you can't change. You're 5' 3". Stand tall and own your space.

Shittles... I need to do some of this stuff myself. Ha!
