After a while there comes the time to evaluate your choices. Are they right for you? Are you enjoying them? Are they doing any good for you?
There is no point on going on forever with something that doesn't feel right anymore. It's ok to give up and instead focus on something more interesting.
There is no point trying to do everything. Just put all the things in order by importance and think how many of those you can keep on doing at the same time. Then just abandon the rest. There is no point on doing a little bit of everything.
Same with the things you might think are important. Thinks that you feel you should be doing, but don't enjoy doing them. Or they just feel not taking you anywhere. It's a bit trickier, there probably is a reason for you to feel that they are important. If it's really important to you maybe there is another more enjoyable way of doing it.
Focus on the most important things to you. Don't try to do everything. And enjoy what you are doing.
