When you have the choice (which a lot of people here do), you should only do things that you think are really exciting and meaningful for you. In case you have doubts (or rather your brain train to rationalize a bit too much), you can always judge with a coin toss if it's worth it or not ! Not the actual result of the toss, no. But as soon as the coin is in the air, you will immediately know which side of the coin you want to appear.
The inputs that I can't not do, and the outputs that I can't not have.
This is a good way to simplify things. I have so many things I want to do. So I ask - am I so compelled to do this certain activity that I can't help it? Or, am I so compelled to get this certain outcome that I can't not make it happen?
If you're struggling with too many things, it's a helpful filter. And you can further filter by asking 'and will that remain true for the next X weeks/months/years' - i.e. was it something that I couldn't not work on 5 years ago? If so then it'll probably also be a can't not 5 years from now.
If you're not struggling with too many options then I don't think it's a good filter, but if you are then it's helpful for stripping your list down to the essentials.
That way i can buy time in the future to work on what i enjoy or find meaningful. At least that's how i think about it lately.
Now choosing job is a multi-variable analysis for me. I pay more attention to the executives.
