I once read two sentences which, in the long run, have come to make total sense to me:
The secret of change is to focus all of your energy not on fighting the old, but on building the new.
One reason people resist change is because they focus on that they have to give up, instead of what they have to gain.
At this point I believe it doesn’t really matter how much you’ve let your self go, or how many times you’ve given up on changing your body. It’s never too late to make a change – or many small changes – and focus your energy on the new things you have to gain, like health, strength and overall well being.
