Thanks for this thoughtful comment, Berk. Brilliant question!
I would ask myself two essential question:
1. Would I be able to do the project with a smile on my face and complete it with the same pride that I complete bigger projects with at this price?
2. Can I see a way to use this opportunity as a springboard to a new opportunity?
If the answer to either question is “no”, don’t do it. Your happiness and growth are worth more. :-)
However, before giving up, I would suggest doing a discovery session with the client in search of bigger problem worth your time.
All the best to you! :-)
