Your attitude is everything. Pick a good one.

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

If you can understand just one thing thoroughly, then you will understand everything.

If you fail, next time fail better.

Tomorrow is worth more than yesterday but less than today.

Success can never happen without the journey (struggle).

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Shoot for the moon and even if you miss you’ll land among the stars/

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

It always seems impossible until it's done.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

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

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

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