Can you hold yourself accountable?

This was huge for me. It's actually the reason why I failed the first time. Every day many people quit on their path, citing reasons like "I don't have time" or "I can't get anything going." Most of the time, the main reason is that they don't hold themselves accountable. No systems are present to make them progress forward or get eager to move on.

When you're excited about your business idea, set up accountability systems right away to help you get going. It could be as simple as being part of a mastermind group or giving a check to your friend to donate to a charity you hate (if you don't meet certain goals), and so on.
