In the past 12 months, I have learnt an awful lot. I am getting there, but it is a very steep learning curve!
It doesn't exactly feel like being back to university; there is very little theory involved here; it is mostly practice!
To brush up on the main aspects of independent publishing, I have purchased The Insider's Guide to Independent Publishing published by the Independent Publishers's Guild.
I hope I will be able to become a member one day...
Beforehand, there is so much to learn.
