What work is worth it to do with 100% certainty? A lot of times these things open up new opportunities even though you might find yourself working on a bust. most times even if it's not valuable from the get go you can always use it when someone asks about your open source contributions or maybe the thing you are working on sparks an idea for another product or gives you some working knowledge of some new library or language that is useful for your next job search.
