So why don't you pick up your phone, make that call now. Why not say sorry to that person you might have wronged right now, why not tell that person how much you love them and how much they mean to you. Why don't you work now to achieve those goals you set for yourself a long time ago. Remember, only this moment is guaranteed, you can never tell what will happen in the next minute, so now is your only chance and the deal is You Only Live Once, make this moment count.

I just made some phone calls now. Such a reminder! Thanks @michellesamson.
