In our community, we help people use skills they already have to make Magazines. The truth is, most people have all the skills they need to do a "bad" version of whatever it is they ultimately want to make or do one day.
Want to run a marathon?
You can probably walk one for now (and get better with time)
Want to write a novel?
You can probably write some short stories or posts for now (and get better with time)
Want to play professional tennis?
You can probably hit the courts and let everyone beat you for now (and get better with practice)
Want to make a magazine (like we do)?
You probably know how to make posts (write) and add pictures (Gifs of whatever). So harness those skills and just do it.
Seriously, who is gonna stop you? Just do it.
If you do something related to the ultimate goal you have, you will slowly get better. So, stop stalling. Stop waiting for permission. Just start.
