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

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

Don’t be afraid to work hard and find out how good you can really be.

Success can never happen without the journey (struggle).

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

We learn more from failure than we do from success.

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

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

It always seems impossible until it's done.

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.

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

He who has begun his task is half-way done. Have the courage to begin!

There are no bad mistakes in maths, only discoveries.

Skills are built not born.
