I'm obsessed with Dungeons & Dragons 5e to begin with. I play and DM (dungeon master) as often as I can afford time-wise.
So, naturally, being immersed into the system and the culture surrounding it, I started making videos about power-builds and character optimization after watching the ol' pal Alex Becker's videos about making millions of dollars on YT lol.
I never expected and won't ever make millions doing this. I'm not operating within a multi-million dollar niche. However, I feel like I'm close to making this YT thing a stable and diversified primary income stream via Patreon, Adsense and affiliate programs in the future.
The hobby seems to be growing so I don't have to worry about immediate longevity. Even if it dies completely, I'll be able to switch into something else. I've always been an escapist and I'll just find another hobby that interests me and transition over there if necessary.
