There is great wisdom in being able to realise that you don’t understand something before it goes too far.

You're not in competition with anyone but yourself. Outdo your past, not other people.

99% of failures come from people who have the habit of making excuses.

We all have two lives. The second begins when we realise we only have one. 

If you can understand just one thing thoroughly, then you will understand everything.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

If you want to succeed, double your failure rate.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Don't fear failure, fear being in the same exact same place next year as you are now.

Don’t hang your targets after you’re done shooting.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Everything that happens was once a dream.

It is never too late to become what you might have been
