Just because you used to love something, does not mean that you are obligated to keep doing it long after you stop loving it. In fact, you are likely doing that something a disservice by not pouring your all into it.
This is exactly why I stopped doing fresh.mn and cinna.mn. It took me a looooong time to get there, though. At the time I attributed it to burnout. Looking back now, I can see that it was a little deeper than that.
