For example: I started doing push-ups with 1 push up per day, I added 1 push up to my target after 3 days until Ihad 20 (after 2 months) . Instead of starting another habit I kept it at 20. Now I am adding crouching with slow increments. After I am comfortable with both pushups and crouches, I will start replacing push up with single arm push-ups.
Once you have that in mind, limit yourself to only adding 1 new task after a week of successfully completing what you have already committed to. This way by the end of the week, you will know if you have extra resources to commit to a new habit.
Most importantly? If you have too many, you can always reduce and refocus. This is REALLY important. If you’re just not able to add in a task yet, it’s OK. Build up your triangles first. Get a streak going. When you are feeling energized, add ONE. See how it goes.
