My top 3 tips would be:
1. Find a niche. Find a topic or subject that you enjoy talking about. That will keep your channel going and lessen the likelihood of you getting burnt out.
2. Start creating now. Don't overthink it. You don't need a fancy camera. 90% of my videos are shot on my phone. You don't need to be amazing at camera work. The more you create, the better you get at filming, editing, and storytelling. I almost didn't start because I thought I needed to build a more impressive resume before reaching out to restaurants and asking them if I could do videos. But I ended up just starting and I can't watch my early videos because of how bad they are. But if I didn't start then, I wouldn't have made mistakes that I learned from. This video was of me a year and a half ago when I started using my phone more for my videos. My hand movement is jerky. I'm in the way of the light source so there's a shadow over the subject. My framing is off. I've learned from this to make current videos better.
3. Third tip is to post consistently. It's going to be different for each person. It could be once a day, once a week, or once a month. Whatever works for you. You should try and keep up with it. It builds discipline but also gives an expectation for your subscribers.
Those are my top 3 tips that I can think of right now. Please let me know if you have any other questions and good luck!
