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

We all make mistakes. What matters is how we choose to move forwards from them.

The greatest mistake we make is living in constant fear that we will make one.

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. 

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

The greatest enemy to human potential is your comfort zone

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

It always seems impossible until it's done.

Time is your friend, impulse is your enemy.

Hope might be a good breakfast, but it makes a very poor dinner

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

You can have results or excuses, not both

We all have two lives. The second begins when we realise we only have one.
