I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Failure to prepare = preparing to fail

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Knowledge is of no value unless you put it into practice.

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

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

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

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

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

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

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

It always seems impossible until it's done.

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.
