You can't enjoy what 'was' or what 'might be'.....so, do yourself a huge favor and start enjoying  what 'IS' - Live in the "Present Moment" - Right now is what's real! Today will soon be a memory/ a yesterday. What will you create as a memory for yourself and someone else who will come into contact with you on their journey today? Make it good.....make it a memorable event....something to smile about!
