Is there an age or year of your life you would re-live?
I do not wish to re-live any of my past for it was destined and bound to happen.
On the contrary I would like to learn from my experiences of the past, work hard on my present, become a better person so that my future is as good or even better than my past.
People may argue that the future is also destined, which I agree, but there is no harm in trying. You never know when the Almighty gets impressed.
Keep Persevering.
