Interested to hear how you got on with this. I wonder if your findings are similar to my own.
I started brand new to youtube with a similar challenge, 100 videos in 100 days.
Albeit I didn't have the experience you have.
I managed 87 of 100 and I was exhausted!
The main takeaways:
Positive: It broke the fear barrier, made me accountable, helped me realise I love creating youtube content and helping people. I also leveled up my skills fast.
Negative: I had never edited or created a video before, I didn't appreciate how hard it would be, I had to put "actual life" on hold and luckily have a supportive wife Quality was awful. In hindsight, less quantity and more quality.
I realised that pressure works for me but 90 / 100 days is a slog especially around other commitments.
I look forward to reading how it went for you and what advice you would give to anyone thinking of trying.
Plus.... Im interested in how you find a membership in comparison to an fb group. I've been thinking a lot about this myself recently and whether to start a paid membership group.
