A lot of what I'm doing has been a learn as I go since I started writing. The book covers and then the book trailers and other videos. I put a lot of hard work into those and yes I did learn a lot as I went. Now however I've learned some really good stuff that I wish I had known when I started.
Yes I could learn to wait and try to find out everything I can before taking on a new project but when you don't know that you need and what's out there you kind of left hanging until someone comes along and introduces you to it.
I at least know that with every new project I take on I will learn more and more.
Have a look.
