I had a similar problem.

* Figure out what do you want achieve in the long run (eg individual freedom, another interesting idea that requires much more capital, fly to space, save pandas etc). Does switching/quiting really help you towards that goal? No matter what idea you choose there will be always some less interesting aspects about it. So you need more than "interesting".

* Are your goals/ideas too unrealistic (=loss of interest)?

* start long distance running (helped a lot!)

* be open about what you do (friends, family)! Social pressure is not that bad in your case :)
