I was only thinking the same thing the other day actually. What motivates other people ? I really enjoy making videos and all that and I guess my favourite thing about it is seeing the finished product ! I mean I know drawing is you thing (I really wish I could draw) but I mean it's the same process I feel. Starting it off in the first place can be difficult, but I kinda get into the swing of it and then I just love it. I do struggle to start making content though.
But I guess my main motivation is just finally seeing the video up online, and getting comments on them, good or bad ! It inspires me to do more and learn from the last video I made and get better at it every time.
