Success as a coach is how you will be remembered by the players, parents and other teams.
Success for the ladies if they improved from the beginning of the year to the end of the year. Have they grown as individuals and as Mark said above if you have helped them to catch the bug to pay it forward, then you did the best you could have most likely. For some the softball is their world away from some pressures on the home front, no matter what level you coach or play....it's their escape, so if they don't enjoy it, we failed somehow....
