It always seems impossible until it's done.

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

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.

Mistakes have the power to turn you into something better than you were before.

Dreams don't work unless you do.

Success can never happen without the journey (struggle).

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

Start, struggle, fail, fix and learn. Repeat.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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

If you can understand just one thing thoroughly, then you will understand everything.
