Are checklists only for the week days? What about the weekends?

We treat weekends as a mini vacation from our real lives. But weekends happen all the time. We can't treat them as vacations all the time. We throw away our routines and along with them our goals. 

I find myself filling my days on the weekend with everything but working out and eating right. I eat on the fly all the time, and even if I am sitting at home doing nothing the gym isn't even in my radar. I wish it was, but I feel like the gym takes up too much of my time on the weekend. I mean going there, working out for a couple of hours, and coming home, showering and getting ready again. But why do I think this takes up too much time on the weekends but not during the week? I mean I work all day and I am so excited to get to the gym, but I HATE it on the weekend. Its the same gym, same people, same equipment, but it still doesn't FEEL the same. Why is that? UGH!

I set my goal, but I don't make a plan. I do everything I can to avoid it. So my goal is never reached. 

I want this to be a lifestyle change and so I have to let it change my lifestyle. I can't be resistant to it. I need to change, if I don't than I am in the same position that I have been in, and I don't want that. 

Will I change more than my lifestyle? Will my personality change? Will my friends see me differently? I don't want this to become my life. I don't want to be the friend that always talks about what they are eating is SO bad for them, or that I need to ditch them for the gym. I need to find that balance, but until then I feel like I will be obsessed with this part of my life. I feel like there will be an unbalance. I think this is why I am afraid to workout on the weekends. I am not ready to give that part of my life yet. I am saving that for my friends.
