We all make mistakes. What matters is how we choose to move forwards from them.

I think, therefore I am.

No one starts out on top. You have to work your way up.

The road to success is like a staircase. If you want to succeed, double your failure rate

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

It is never too late to turn an unproductive day into a productive one.

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

Run in the morning before your body figures out what you're doing

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. 

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

The wise person knows that no answer is also an answer

Procrastination makes easy things hard and hard things harder.

Success can never happen without the journey (struggle).

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

Success is a journey, not a destination.
