The easiest person to deceive is yourself.

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

It always seems impossible until it's done.

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

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

You can have results or excuses, not both

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

99% of failures come from people who have the habit of making excuses.

The power of reflection is the most powerful skill you’ll learn.

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

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

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