This sounds extreme, but none the less I agree people should try to change something.
Most recommend to start exercising. Easiest way to do this is to simply say I'm the kind of person that runs / bikes / works out (don't give yourself the option to decide). Simply say on Saturday's I do a run (rain or shine), then say Tuesday's and Saturdays, etc. In no time you're doing it 3+ times a week.
From one good habit others will follow, since you'll have learned how to stay consistent.
For me, what worked was making a commitment to literally go to the gym everyday after work. Whether I actually exercised or not could falter on a day-to-day basis, but without fail I walk into the building. As predicted, it means I get a workout in at least 4 days a week, because if you're there, the barrier to "might as well run" or "guess I'll put in a quick weight set" is much lower.
it's good advice to tell yourself that "I'm the kind of person who does X." We can shift/expand our identities about ourselves to build better habits. It's like, to quit smoking, we must remind ourselves that "I'm not a smoker/ a person who smokes anymore."
