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

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

Failure is NOT your destiny. Failure is the key to success.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

There are no shortcuts to any place worth going.

Everything that happens was once a dream.

Procrastination makes easy things hard and hard things harder.

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

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

Our fixed mindset builds our cage, fear keeps us in it.

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

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. 

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