Scope a side project you can actually finish

This prompt helps you cut a project idea down to something you can finish in your spare time, given the hours you have each week.

I want to build [PROJECT IDEA] in my spare time. I have about [HOURS] hours per week for [WEEKS] weeks and my skills are [SKILLS].

Define the smallest version that is still useful, list what to leave out for now, break the work into weekly deliverables, and name the three most likely reasons I will stall along with how to prevent each.

Cut the scope in half once more before you start; most side projects die from being too big.

What you will get

The smallest useful version of your idea, a list of what to leave out, week-by-week deliverables that fit your hours, and the three most likely reasons you will stall with a way to head off each.

Common mistake

The plan needs far more hours than you have.

Fix: Give your real weekly hours, not your best week, and say “if the plan does not fit, cut features instead of adding weeks”.

Also watch for

The smallest version is still a full product. Ask “what could I show one person in the first two weeks?” and treat that as version one. Everything else goes on the leave-out list.
The stall reasons are generic, such as losing motivation. Add your history, such as “I usually quit when I hit the design stage”. The AI can then give a specific guard for each reason.

Try a variation: add a stop rule

Ask for “a clear rule for when to pause or stop this project, based on my hours and the weekly checkpoints”. Deciding the exit in advance makes it easier to keep going or to quit cleanly.

Cut the first version in half again. Show me the new weekly plan and what I can demo to a friend at the end of week two.
