I have ADD and PTSD, which sometimes helps me excel, and other times helps me recognize some obstacles. I have a simple five step plan for just about everyone and everything
1. Go, make something happen.
2. Do work you're proud of.
3. Treat people with respect.
4. Make big promises and keep them.
5. Ship it out the door.
When in doubt, see #1.
I'm moderately competent and overly confident in what I do. I come prepared with exactness and drive. Sometimes too much drive!
