Don’t worry about where to start. Remember, it’s the decisions you make, it’s the decision to get started it’s the decision to face possible failure, it’s the decision to get up once you’ve failed and it’s the decision of what to learn when you fail.
Don't worry about getting it right. Just get it started.
If you can't sleep, then get up and do something instead of lying there and worrying. It's the worry that gets you, not the loss of sleep.
Our thoughts make us what we are.
