Failure to prepare = preparing to fail

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Everything that happens was once a dream.

Everything you want is on the other side of fear

The greatest enemy to human potential is your comfort zone

We learn more from failure than we do from success.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Failure is NOT your destiny. Failure is the key to success.

Your attitude is everything. Pick a good one.

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

The greatest mistake we make is living in constant fear that we will make one.
