Recently some people I +watch leave dA or taking a break. I do understand them since I was in the same boat for years. Going hermit mode is nice and useful sometimes. You'll reconnect with your inner self, find your goals, got an enlightment and so on. But the thing is you guys just didn't realize how much the community benefits you when you share your passion.
I put my best effort into each piece and enjoy the feedback no matter the scope. Even if there are just a few comments, someone will say something that makes me nod and smile. Sometimes it turns into nice conversation or rave chat. I love it. And I won't be able to experience it if I'm out.
The community around you is your reflection actually. If you share joy, happiness and excitement in your works, boy you'll be amazed how wonderful the community is. Think of chain reaction - you spread a small impulse that turns into a massive wave.
The choice is always up to you, just keep in mind that you're not alone. Don't retain your passion for yourself only, share it!
