Never give up, or resign yourself to a negative life - you are worth more than that. Start with what is upon your desk - it's as good a place as any. Don't wait to be inspired - inspire yourself.
To anyone suffering from writer's block, I could not recommend a solo trip more. Over 41,000 steps later, I am over the moon with how I feel after my adventure. London is a great location, because there is so much to see and do, but anywhere that will get your creative juices flowing is worth a visit. Wherever your muse lives, seek it out, because you won't regret it. I'll certainly be doing it again!
