Everyone will make mistakes in business. It is not an exact science.
The trick is to make less mistakes than anyone else.
How do you do that?
Discipline. Concentration. Learn.
Stick to good habits: early to bed, exercise, meditate.
Concentrate: don’t let anything distract you from your focus.
Learn: read books. Find mentors. Watch others. Learn from your own mistakes.
Do all of that better than your competitors and you’ll make fewer mistakes.
