Definitely same here. I started working on some personal projects for Github this winter and ended up getting a long streak of about a month from it. Since then, I've been in the habit of getting long streaks and try to do 2+ commits every day, but as soon as I fall off that streak it takes me 2-3 days to think about contributing again. Not only does it motivate me to write code (almost) every day (which I'd argue is important to developing programming skill), but it also pushes me to share code I was already going to write, which I think is a win-win for everybody.
