You can have results or excuses, not both

There is no elevator to success, you have to take the stairs.

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

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

The master has failed more times than the beginner has even tried

Success is not final and failure is not fatal. It is the courage to continue that counts.

Mistakes have the power to turn you into something better than you were before.

I think, therefore I am.

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

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