If you're going through hell, keep going.
Begin to be now what you will be hereafter.
You never know what motivates you.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
Well done is better than well said.
After a storm comes a calm.
The most effective way to do it, is to do it.
Wherever you are - be all there.
Be gentle to all and stern with yourself.
If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
