How to Decide Between Multiple Side Projects (When You Cannot Do Them All)
Three exciting ideas, ten hours a week. Here is how to pick the one with the highest leverage, instead of doing all three poorly.
You have three ideas. They are all interesting. They are all things you would actually want to build or pursue. You have ten hours a week, maybe twelve in a generous month. You know — you really know — that doing all three at once means doing all three poorly, and that the smart move is to pick one and commit. You also keep starting all three anyway, because committing means giving up the other two, and you do not want to give up the other two. The problem is not that you have too many ideas. The problem is that you are evaluating them on the wrong axis — usually how exciting they are right now, which is the least predictive variable for which one will actually pay off. The projects most likely to produce real returns are usually not the most exciting ones at the start. They are the ones with the best leverage on what you already have.
What follows: how to evaluate side projects by leverage instead of excitement. Then a tool that ranks them.
Score each project on what it leverages from your current skills
A side project that uses skills you already have produces results faster than one that requires you to learn something new. The fast-results project sustains motivation; the slow-results project loses momentum after week three. For each project, ask: how much of this draws on what I can already do, and how much requires me to acquire new capability before producing anything? The high-leverage project usually wins not because it is more ambitious, but because you will actually finish it.
Score each project on what it produces beyond itself
Some projects produce only the project. Others produce skills, network, audience, or material that enables future work. A blog post that argues your thinking on a topic produces the post — and also positions you, builds your audience, and clarifies your thinking for adjacent projects. A product launch produces the product — and also a network of users, a feedback loop, and credibility. Pick projects with positive externalities. The project that only produces itself has lower expected return than the one with a broader payoff surface.
Honestly estimate the time, then double it
Side project time estimates are universally optimistic. The project you think will take four weeks will take eight. The one you think will take three months will take six. Multiply your gut estimate by 2x — sometimes 3x. Then ask: am I willing to commit that much real time, given everything else in my life? Most side projects fail not because the project was wrong but because the original time estimate was a fantasy. Estimate honestly and many of the close-call projects become obvious nos.
Pick one — and put the other two on a list, not in your head
Once you have ranked the options, pick one. Put the other two on an explicit list of projects-not-being-pursued-now. Writing them down does two things: it acknowledges their value (they are not forgotten) and it removes them from the active mental load (they are not competing for attention). The list becomes a queue for after the current project finishes. Most attempted-three-at-once failures are about the lack of a queue, not about the inability to focus.
Set a real review point, not an open-ended commitment
Commit to the chosen project for a fixed time — eight weeks, twelve weeks. At the review point, decide deliberately: continue, switch, or stop. The fixed window prevents you from feeling like you have signed up forever. It also prevents the other two ideas from constantly pulling at you, because you know they will get a turn at the review point. Open-ended commitments fail because the brain treats them as permanent and rebels. Bounded commitments succeed because the brain trusts the boundary.
