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

Skills are built not born.

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

Tough times never last, but tough people do.

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

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

Procrastination makes easy things hard and hard things harder.

Fall down seven times, stand up eight.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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