Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

I have not failed, I've just found 10,000 ways that won't work.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Failure to prepare = preparing to fail

The wise person knows that no answer is also an answer

Procrastination is the thief of time and the enemy of success.

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. 

It is never too late to turn an unproductive day into a productive one.

Hard work beats talent when talent doesn't work hard.

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

Failure is not the opposite of success, it is part of the success.
