What you do today can improve all your tomorrows.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
You never know what motivates you.
Go for it now. The future is promised to no one.
Well done is better than well said.
Begin to be now what you will be hereafter.
Failure and things of this sort - you can take it one of two ways. You can either let that hurt you and really affect the way that you live your life in the future, or you can use that as an opportunity for growth.
