Self-confidence is the first requisite to great undertakings.

If you don’t ask, you don’t get.

Persevere and get it done.

Our whole life is solving puzzles.

It’s pain that changes our lives.

No great thing is created suddenly.

Life is short and progress is slow.

In the middle of difficulty lies opportunity.

I’m a slow walker, but I never walk back.

Victory belongs to the most persevering.

Perseverance, secret of all triumphs.

The journey of a thousand miles begins with one step.

Perseverance is a virtue that cannot be understated.

Thankfully, persistence is a great substitute for talent.

Nothing is permanent in this wicked world, not even our troubles.

A man will fight harder for his interests than for his rights.

Persistence is to the character of man as carbon is to steel.

I was taught the way of progress is neither swift nor easy.

Don’t quit. Suffer now and live the rest of your life as a champion.

It’s not that I’m so smart, it’s just that I stay with problems longer.

It is the cheerful mind that is persevering. It is the strong mind that hews its way through a thousand difficulties.

Perseverance is the hard work you do after you get tired of doing the hard work you already did.

Through perseverance many people win success out of what seemed destined to be certain failure.

Patience, persistence and perspiration make an unbeatable combination for success.
