I am having the same issue myself. Between school and 2 jobs, my motivation is gone by days end. I am at the point now where I only workout Saturday and Sunday. Not getting the results I want. Does anybody else live a hectic lifestyle and still find the motivation to keep going throughout the week?
Don't give up about something you want .. and don't ever thinking about giving up .. it's the time to do you want .. to do what you love .. remember that thing or things that you wanna do will change your whole life .. work hard and harder
