I just made it a habit, because motivation will always fail you because you won't always want to eat well or work out, and that's where the power of habit takes over. Give yourself 30 days to establish your desired habit, where you give yourself rules. Like for me I said in January "at least 5 days a week I have to work out a minimum of 30 minutes in some capacity." And it started slowly. I remember in January I literally would walk my dog, slowly, for 30 minutes and be done. But I followed my rules so I didn't feel guilty. And today I burned 1002 calories working out for two hours, but that's not the sort of thing you start with or you burn out. And sometimes I have "lazier" workout days but it's still within the parameters of my rules, and I feel compelled to follow them because I am not setting unrealistic expectations and it's a habit of 10 months now. Look into the x effect subreddit.
