Guys, if you are writers, stop what you're doing right now and read this.
Or if you don't have time, just read this bit:
What’s the worst that can happen? You never get published or the book of your heart tanks, and you never reach your goal, but at the end of your life you look back and say, “I had a dream and I fought for it, I believed in myself and my work, and I never, ever gave up.” That’s a life well lived, folks, a helluva lot better than, “I had a dream but it wasn’t realistic so I quit and watched television.” Do not let reality push you around, do not be sensible and kill your own dreams, and for the love of God do not let people who are only guessing about what’s going to happen next tell you that you’re a fool for believing in yourself and your stories.
If you want to write, or worse again, if you realised when you were young that you wanted to write and like an idiot, actually told people - then you'll be familiar with the awful phrase 'Yeah, but what do you really want to do?' That drives me especially nuts, because it goes beyond suggesting that doing it is stupid - it implies that dreaming of it is stupid.
Not so much, actually. Someone has to make it. And if we're one of the 99.9% who don't, who cares? Once we tried, once we went for it, who can say that it's a waste of time?
