Managing my time as a writer

Get-organisedMy never-ending problem has always been how to organise myself. Last year I finally made the decision to truly commit to writing, and by commit I mean make it a real part of my life. I started writing every day, took two courses, joined a writers’ circle and began to read as much as I could about the craft. In short, I let go of the idea of success and focused on the process. However, what I’m finding now is that there is so much non-writing ‘stuff’ that is necessary to do in order to become a good writer, that I’m sometimes overwhelmed and not really sure how to prioritise, and the more time I have, the more difficult (bizarrely) this seems to be! I tend to feel that everyone else seems to have got this time management thing worked out?  Any ideas/advice?
