Accountability and bucket lists
I just finished a triathlon with my son and his wife. For me, it was a bucket lister, given my 15 year retirement from such events; for Sam and Brittany is was a beginning. Training for the Grandman an old lesson on accountability came to mind.
So if you really want to achieve something hard, announce it to your circle of friends and choose one as your accountability partner. You’ll be off to the races.
