During my over 50 years of electronics both as a profession and as a hobby, I have designed and built countless projects. With very limited occasions, where the project's budget has spiraled out of control or is taking way too long, I always complete my projects. Even if my original estimations proved to be too optimistic, or if the actual performance doesn't meet expectations, I complete the projects. After all, one gains more experience from difficult projects than the ones that work on the first attempt.
Nowadays however, I am on my third abandoned project on this year. After struggling with the troubleshooting or the assembly, I simply lose interest. Since this is a hobby, which is supposed to be a pleasurable endeavor, I don't pressure myself to complete it.
This doesn't mean that ideas don't keep coming, they do and plenty. I look at datasheets, search on the internet, fill my booklet with sketches. But right now I have imposed on myself a "project freeze" until I come out of this lethargy.
Have you suffered such a syndrome?
