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

It always seems impossible until it's done.

Nobody said it’d be easy, they just promised it would be worth it.

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

Tomorrow is worth more than yesterday but less than today.

There are no bad mistakes in maths, only discoveries.
