I agree with 1. that works for me as well. With regards to 2. that has never worked for me by itself, unfortunately. What I do instead is to find a way to be intrinsically motivated. For example, with exercise I notice that the gain in alertness feels like drinking coffee. So I now tell myself to drink coffee (and by that I mean exercise), that really works well in my particular case and makes me intrinsically motivated to exercise as the alertness gained by exercise is its own reward. Though, I do need the right setup for this, I'm currently house sitting and I'm not exercising because I don't have my weights. So how habit formation for me does help is that the more I practice a routine, the easier it is to execute. Which is why I'm not exercizing right now as I'd need to do body weight exercises and I'm used to weight exercises.
