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

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

Lose an hour in the morning and you will spend all day looking for it.

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. 

The temptation to quit will be the greatest when you are about to succeed

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

He who has begun his task is half-way done. Have the courage to begin!

The greatest enemy to human potential is your comfort zone

You can hire a tutor but you can't hire someone to practice for you.

Success can never happen without the journey (struggle).

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

Procrastination makes easy things hard and hard things harder.

Tomorrow is worth more than yesterday but less than today.

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