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.

Worse still, you may be preventing someone, somewhere, from doing that something you are doing and no longer loving. It could be something that they would really love and you are taking up their space.

So, if this is you and you are no longer in love with what you do, stop doing that.
