Adam Gurri:

The perfect balance is committing to only those crafts that you can perform with satisfaction even if you have to do so in utter obscurity.  Then, put your work out in public as part of the process itself -- if you're making homebrew beer or an Arduino hack, make a video or write about the process as a means to think harder about the details of it.  If you're a writer, think of putting it online as simply having the work backed up in one more place.  In this way, you open yourself up to the spectrum of possibilities, ranging from utter obscurity at one end to global fame at the other.  Far more likely is something closer to the obscurity end but much more satisfying -- that you will draw the attention of a relative few who share your interests.
