Devote yourself to learning something new about your field of mastery every day.
An amazing performance is always a reflection of awesome amounts of practice.
Other people's opinions of you are none of your business.
If you're not scared a lot you're not doing very much.
You would not have the wisdom and knowledge you now possess were it not for the setbacks you have faced, the mistakes you have made and the suffering you have endured.
Run your own race. Who cares what others are doing? The only question that matters is 'Am I progressing?'
