I've tried sitting around and planning videos and I found that doesn't work for me. So now I let the video ideas come to me, rather than trying to force them. So I could be walking the dog, laying in bed, eating dinner or having a conversation with someone and something that happens, something I think about or whatever will prompt an idea which could be for a vlog, sketch or challenge.
From there I'll make a very brief note on my phone of what the idea is, enough information so I can understand it later and then when I'm back at my PC I'll write it down in full detail in my "Video Ideas" notepad file. Then, at some point, I'll make the video.
I've had something in that file that has been there since last year, but it requires more footage and things like that before I do it. It's nothing super fancy, in fact, it's just a channel trailer so it wasn't really an "idea" in that sense, but, it's something I have plans for and things I want to specifically do in that video.
But yeah, I just let the ideas come to me and then create the videos when I can. (Though still uploading once a week on a Sunday)
- I realize I perhaps went a little off the whole thing there, so TL;DR -
I keep notes on my phone when I have an idea and write it up in more detail in a notepad file when I am on my PC.
