I read a line in a motivational training video that simply states, "Don't Postpone Joy".  Busy schedules, work, carpools, school functions and the like can sometimes lead us to do this.  Remember to take in a moment that brings you happiness and joy when it occurs and make it last as long as possible.  Our inventory of these types of moments seem to run very limited at times and we need to do a better job of allowing ourselves to appreciate them when they occur.  Sharing those moments with your inner circle can also help, in that they can remind you to look forward for the better days ahead.  We take pictures of children when they are babies and through out their lifetime.  When we get to view them again as time has passed they usually bring a smile to our face, as we recall the joy that existed in that moment of that photograph. Practice that ability to retain, live and experience your own daily joy as often as you can.
