Writing is usually a solitary task - unless you count the phone calls, emails, fur kids, real kids, partners, parents, BFFs, bosses, colleagues, housework etc that stick their bib into your business whenever you're trying to write, If you don't count all of those.....it can be quite an isolating occupation. And because there's just you (mostly) it's easy to lose faith and start doubting yourself, your work, your talent, your calling, your goals, your choices, your future. Actually everything. You start doubting everything.
So it's nice to find an article written by a writer for writers that gives you that little boost. It may not dispel all your deepest darkest fears (that's what therapists are for people......that or writing a novel) but it goes a long way to making you think "hey maybe I can do this or at least give it another shot".
There are two posts by the same author - Po Bronson. The first is called Advice on Writing and the Writing Life and the second is called My Basic Philosophy (as it comes to Writing). Both are beautifully written and have given me the lift I needed today. Hope they do something for you.
