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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Don't fear failure, fear being in the same exact same place next year as you are now.

It always seems impossible until it's done.

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

Lose an hour in the morning and you will spend all day looking for it.

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

The temptation to quit will be the greatest when you are about to succeed

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Everything that happens was once a dream.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

We learn more from failure than we do from success.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Success can never happen without the journey (struggle).
