Just because you don’t know how to do something, doesn’t mean that you are not qualified to do it try it. I’m not saying the results of your trying are going to be good but don’t let your lack of knowledge be the reason you don’t do it.
I’ve been trying to thing of some abstract way to make this point but I can’t some up with anything that I feel helps make my point without getting lost in my own thoughts. So I will use myself as the example.
A little over a year ago I had never edited audio of video. Looking at today, I have a rough idea of the basics of audio editing and I am not afraid to sit in front of a video editing program and see what I can do.
There are barriers to doing what you want to do and not knowing how to do them should not be a real barrier. Are there other barriers that can hold you up? Of course, and if you don’t currently have the available time to get over the initial learning curve, fine, come back later. If you have the passion and the time to learn it, learn it, make your thing badly. The pride of creating a thing is a drug. The same way I felt when we finished building a picnic table in High School is the same way I feel when I’m done with a podcast episode.
Letting the lack of knowledge stop you from doing is dangerous. Not knowing how to do something is ok, figure it out if that is what you need to do.
