I think the all or nothing mentality is really holding a lot of people back. I know I can’t do that kind of thing personally and always build my habits slowly. Want to go full veg? Give up one animal a month. Want to learn woodworking? Add one new tool (and only one!) each project. Want to run every day? Start with once a week and build. Also don’t get all flustered if you miss one. Just do it the next day, don’t consider yourself defeated and give up.
