If you continuously compete with others, you become bitter,
but if you continuously compete with yourself, you become better."There is no race... there is only a runner.
You are the runner.
You should run as hard and as fast as you can.
Ignore the other people on the course, because they are using a different clock, a different distance, a different race.
Stay in your own race.
Be happy with the life you have chosen for yourself, and live it fully.
Leave others to theirs.
