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

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

Don’t hang your targets after you’re done shooting.

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

It doesn’t matter where you start, it matters how you end

Success can never happen without the journey (struggle).

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

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

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

If you want to succeed, double your failure rate.

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

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

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

Skills are built not born.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day.
