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

Everything that happens was once a dream.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

I think, therefore I am.

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

Success is the sum of small repeated efforts, day in and day out.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

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

Practice like you’ve never won. Perform like you’ve never lost.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

There are no bad mistakes in maths, only discoveries.

Instead of finding reasons why you can't, find reasons why you can.

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

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