"The reason people find it so hard to be happy
is that they always see the past better than it was,
the present worse than it is,
and the future less resolved than it will be."
Instead...I hope you cherish the past, live and love the present and embrace to the future.
There is a LDS Hymn that I think says it all...
(Praise to the Lord, the Almighty pg. 72, 4th vs)
"Hast thou not seen, how all thou needest,
hath been granted...."
Its natural to think..."Life would be better if only I had"....or "Things would be better if only I could"....but if we could only realize that we already have everything we would ever need for this time in our lives, how much stronger we could be to face our adversities, how much brighter our out look on life would be and most of all...we would be HAPPY.
Blessings aren't material....step back and try to see the blessing you have so abundantly received and remember today, all that you could ever need-you have already received.
