With a 5 year old, 3 year old, and a wife that's 8 month's pregnant, actually finding the time to cast once is a success for me!!! My most successful fishing trips lately have been taking my kids to my in-laws pond and getting them to catch little bluegills or not catch anything. They have fun regardless. Success in my book!
A fishing trip can be a success without catching anything for numerous reasons. If you like to just "experience" nature, peace and quiet, relax, have fun with friends, "destress", etc, etc, etc then just the act of fishing meets that goal and is a success.
Not everyone is hypercompetitive with an eye always to the scoreboard.
