It always seems impossible until it's done.

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

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. 

Success can never happen without the journey (struggle).

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

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

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

Tough times never last, but tough people do.

Start, struggle, fail, fix and learn. Repeat.

Hard work - a two way street where you get exactly what you put in.

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

Just stick with it, what seems hard now will one day be your warm up.

Your limitation - its only your imagination.

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.
