Yesterday I had a telephone conversation with a writer who has been accepted for a demanding writing workshop. Before I could say congratulations, he confessed that he was wavering because before he signs on he wants to be sure he's going to have the support he needs at home.
I hope I got across my feeling on this, which is: writers must manage to keep writing, support or no support. Despite what those around us think or do or say. Truth is, even the most well-meaning friend, spouse or other relative, who thinks they are being "supportive" will often say or do or imply just the very thing which derails us.
So why let a thing like support get in the way? As for unsupportive folks, please ignore them and carry on.
And, I also recalled that I had posted something about this very thing last year. I thought it could use repeating. You can find that post: Writers' Complaint Department: Stress and the Support System, here.
