Following up on katzgrau's recommendation for "The Power of Habit", I think it's important to stress that you should prioritize and choose the most important habit first and focus on that 100%. In the book, Charles Duhigg mentions "key habits" that, if changed, will lead you to change other habits as well. I've been down the road of changing habits multiple times and I think the most important habit you can adopt is actually to continuously watch your progress, adjust your routines if necessary and, more generally, give you time to think about where you're moving with your life on a grand scheme of things. Whenever I tried to get into a new habit, I found that the hardest thing was actually to come up with and take counter-measures if the routine wasn't sticking as expected. I would often try a new routine and if it failed to stick, I would automatically fall back into my old (bad) routine. So my advice is this: Set aside time to reflect upon your routines (and your life in general). Make this your very first habit to get into. Personally, I've found that doing it once a week is by far not enough for me (and it's also a difficult habit to maintain), so I decided to do it once a day and, since I rarely find the time at night, I decided to get up a bit earlier in the morning and go for a 30min walk. This has the added benefit that you get a bit of exercise and lots of fresh air. I also use that time to decide on my most important task for the day that I will work on right after the walk.
