I have historically had a hard time sticking to things. I have a tendency to pick up a new tool or habit and then just as quickly put it down. One of the things I most admire in my wife is her discipline. She is up at 4:30am most mornings to swim in icy Lake Washington, rain or shine, year-round. I have been fortunate to have succeeded despite not being a particularly disciplined person, but as I approach 30 I think it’s as good a milestone as any to make a change.
