Given that you have discovered your purpose and you know how to go about achieving it. You are willing to give it all you have, there would still be time constraints, given that time doesn't wait, there are bound to be distractions, disappointments, time set
apart for God, family, friends, work, study and socials.
If this is the case for the man who has foresight and is working tirelessly towards his goal, how hard is it going to be for someone who is still trying to find out his life's purpose, worse still, a poor manager of time?
Time that is not set apart is lost, time not deliberately managed is wasted. Time destroyed can never be recovered. There are things that, if you don't give the exact amount of time to, you may never achieve.
It is true that time is money but most especially, time is life.
