Time is free, but it's priceless. You can't own it, but you can use it. You can't keep it, but you can spend it. Once you've lost it you can never get it back.
How much time are you going to be given on this earth? Nobody ever knows the exact answer, which is the reason why we have to make the best use of every single moment that God gives us to breath. These are moments to promote positive growth within our self and the people around us. You don't have to be a motivational speaker to affect positive change in the people around you.
