So life I think is like surfing in the ocean. You have a little control but mostly you are at the whim of the massive ocean and it's energy and you just have to ride the waves.
If you fight it, you die or get injured or pummeled.I've seen now life has peaks and troughs. Enjoy the good times, prepare for the bad times and ride the bad times out, because things will get better.
Don't waste your time worrying about stupid little things or stuff 10 bridges down the road. Do what you have to do, but enjoy your life. Don't live in fear and panic.
