I don't know whether its the same for everyone on Youtube but having a channel kinda makes your life better to a degree. (I know there are demerits as well). But I have learned a lot from being on YT even as a niche channel

Makes you think and innovate.

- The search for content forces you to think and do things you wouldn't do. I went camping.
- It gives you discipline.
- You get courageous (vlogging)
- You learn how to tell stories
- You learn how to speak
- You learn how to edit videos and photos
- You learn how to write copy

- Your channel becomes a portfolio to pitch things.
- You find business contacts (I have gotten work from being on Youtube).
- I use Youtube to sell my courses etc.
- Makes you a credible resource for something.
- It becomes a good way to keep your memories alive

- A reference point for your people/ you in future. Imagine being 70 looking back at your videos at 25
- A creative release. Money aside. You can create work that you love and store it here. Just for yourself

I know not everyone can do YT but its a value adding platform.
