No one else gives a shit.
Say that line out loud and feel it sting. No one else gives a shit, about your "thing," your project, your quaint little life and/or hobby. Now realize what that line is really saying, no one ELSE gives a shit. They don't, they won't, they can't, its not a failing, its just petty human nature and when we expect more from others than not really giving a fuck about our "thing" we are setting ourselves up for disappoint and failure.
No one ELSE gives a shit!
You have to give a shit about your "thing." You have to scrape and advocate, and look out for your "thing" like a mother bear ready to rip a throat out.
