A great piece of advice comes from "7 Habits of Highly Effective People" which basically boils down to "Focus most on what you can control and only a little on what you can influence. Spend as little time as possible worrying about what you can't control or influence." This is referred to as the Circle of Concern sometimes.
With that in mind, focussing on content creation - you can control what you produce. You can probably influence how people engage with it to a certain degree.
You can control your schedule, even though sometimes finding time is hard. Trying to make time is important.
And yeah, you nailed it. Consistency is pretty important. I haven't been able to arrange my schedule to fit decent YT production yet, so I'm still trying to crack that myself. Heheh. Hopefully this year I can find a way to put more time into YT.
