Before bedtime, I would write down in a journal what ideas you tried that day, and if you reflect on these a bit as you fall asleep, you could dream about one or two of those ideas. In the morning, re-read the journal entry you wrote the night before & ask yourself if you want to try pursuing that idea any further that day. Listen to yourself, if you can. Eventually, one of the many ideas you have will start to "stick" and then start to snowball after a few weeks of concentration. I think video creation is a great skill to have even if you dabble in it for a few weeks before losing interest.

I, too, jump interest to interest. A few of those ideas will really stick with you if they really resonate with your life pursuits. This is normal.
