Is passion really enough?

Tbh passion is all I've got. But at the same time I cant help but keep doubting myself and wonder if another project/topic would "work better" and so I end up keep jumping around.

Is it really true that as long as I am passionate and of course learn as I go, that I'll eventually get somewhere?

I only got a few videos in and got some subscribers already. I just don't want to dive in and have it go nowhere.
