I don't think it's possible to sustain any success if you're being completely fake. That said, no matter how real you are, no matter how passionate about your niche you are, you're going to have to eat some shit somewhere and fake it to some extent. For instance, I love doing youtube and I don't have to fake much of anything to do it, but part of the promotion is social media which I detest. I think posting pictures on IG of stupid shit that comes to your mind is narcissistic, vapid, pathetic, loserish, bullshit. The people on Reddit mostly make me want to puke. Twitter is a cesspool of bots and malcontents. Facebook makes my skin crawl. But it all kinda goes with the territory. Nothing comes without sacrifice.
