Whenever you find yourself doubting how far you can go, just remember how far you have come.

Try and do one thing each day that you would really rather not do.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Success can never happen without the journey (struggle).

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

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

Pure mathematics is in its way, the poetry of logical ideas.

We are all maths people : step 1 - do maths and step 2 - be a person. 

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

Success is a journey, not a destination.

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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