Exercise - For me, it's something that I know I need to do, but I really don't enjoy doing it.
My plan of attack is to get my exercise in the first thing in the morning. Once it is done I can breathe a big sigh of relief and not have to worry about it for the rest of the day.
I work full time and have a daily 2 hour commute. Fitting in my exercise in the morning helps get the day started off right.
