Skills are built not born.

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

You cannot escape the responsibility of tomorrow by evading it today

Everything you want is on the other side of fear

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

The wise person knows that no answer is also an answer

Success can never happen without the journey (struggle).

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

Failure is not the opposite of success, it is part of the success.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Procrastination makes easy things hard and hard things harder.
