The great test of heart.

It hurts, keep going.
Push through the pain or work around it.
Find the extra: the extra motivation, the extra desire, the extra intention, the extra energy and keep moving forward.

If you get knocked down, get up.
If you get knocked down again, get up.
A third time, get up.

Don't give up, work a different strategy and follow the path.

I've realised that if you want anything in life, not only fitness, you need to push for it and work hard. Even when you feel fatigued or like quitting or you're injured.

You have to push to achieve and take from life the opportunities you seek.

Otherwise you procrastinate, stagnate and then in a blink the opportunities are gone, the ability and drive will lapse, leaving you with only regret.
