Go for it now. The future is promised to no one.
The secret of getting ahead is getting started.
Begin to be now what you will be hereafter.

If you're going through hell, keep going.
Wherever you are - be all there.
The most effective way to do it, is to do it.
If you think you can do it, you can.
The dog that trots about finds a bone.
