Success can never happen without the journey (struggle).

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

We learn more from failure than we do from success.

Never underestimate the importance of small steps. small steps = big changes. 

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

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

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

Shoot for the moon and even if you miss you’ll land among the stars/

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Don't fear failure, fear being in the same exact same place next year as you are now.

Your attitude is everything. Pick a good one.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

If you want to succeed, double your failure rate.
