Nice thoughtful post. Many truths have been "discovered" by many different religions and schools of thought :) This reminds me of advice I give to young parents. New parents often will say I can't wait until ... he walks, she speaks, he starts kindergarten. I tell them enjoy every day. The joy is found in the the journey of your child growing up. Don't always be waiting for the joy to happen. It is happening now. Enjoy today.
Wise words indeed!
Just as for parents, I can remember looking forward to my 'milestones' - driving a car, being allowed to date, going off to college, finding my 'true love' - always something in the future! Along the way many people told me to live in the moment because that's where joy lives. It has taken me this long to put it into practice!
