Don’t be in a hurry to publish
It is so easy to publish now. No longer are manuscripts waiting for months and years as hopeful authors query agents and publishers. But that waiting time served a purpose. All the while, most authors would be looking again and again at that manuscript, not just picking up errors of grammar and spelling, but noticing that discontinuity, realising that that part needed a bit of explanation, noticing the awkward sentences and smoothing them out. The story was polished.
Take your time, get it perfect. Wait a month, and have a look at it again. Wait a couple of months, go back to it, and only then, when you’re totally satisfied, should you publish. It is a lot more important to do it right than to do it quick.
All the best works of art take time to form – sometimes a very long time. My best book was completed around five years ago, and was only published October, 2011. That was 'Not a Man.'
