New habits: Diabolo every day

I'm trying to learn to create or modify habits. I searched for tips on the Internet, and I'm going to try them, one by one.  The one I'm practicing now is to think about why you want to create or modify this habit. For the habit, I chose playing outside with my diabolo every day. The reason for that is because it's part of learning to help improve the community life in my neighborhood.

I've read and heard that it takes about three weeks for a new habit to be established. It's been almost a week now.
