No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

The bad news is time flies, the good new is that you're the pilot.

The journey of a thousand miles begins with one step. 

Time is your friend, impulse is your enemy.

Success can never happen without the journey (struggle).

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

There are no bad mistakes in maths, only discoveries.

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

You can hire a tutor but you can't hire someone to practice for you.

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

Procrastination makes easy things hard and hard things harder.

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

Everything that happens was once a dream.
