It's silly. A writer's block is an extremely silly situation. The added fact that I'm only 24 and I've already dealed with quite a few writer's blocks is even more silly.
Wikipedia says: Writer's block is the phenomenon in which a writer temporarily loses the capability to continue writing. It is characterized by the loss of inspiration or confidence in creativity. For me, it constitutes the inability to make my story go on, because my characters are mixed up with either each other or the plot. Told you it was silly.
I know what you're thinking; I'm the writer, I decide what happens to the characters and the plot. Unfortunately that's only true up to a certain point. I'll try to explain. For the story and the characters to be believable and to make sense, I can't just do anything I want. If the hero of my story hides from his enemies, this immediately has consequences. His hiding says something about him. It could mean that he knows that they're stronger than him, and he's biding his time to take them out later one by one. It could also mean he's afraid of them. If my hero is neither a coward, nor smart or patient enough to bide his time, he shouldn't be hiding. This was just an example.
Right now, I'm wrestling with my main hero again, Jareth. Ever since Remmelt pointed out to me that he was behaving like a sissy (very logical, since he behaved a bit like me), I tried to rewrite him to make him more manly and powerful. I'm rather happy with the result, I even managed to give him motives that drive him forward (he wants revenge for the terrible accident that happened to his best friend) and with a little tweaking I also made him a powerful and fearsome mage.
My next problem is predictable and a real "D'oh!", to speak with Homer Simpson. The next logical thing Jareth would do is find the person responsible for his friend's accident and make him or her pay. The problem is that this person is of course a vital character for the story; it would kill the plot if Jareth got rid of her. Luckily Jareth is not overly smart, so I might be able to find a way around this problem. It's still silly, though.
Luckily, my roleplay friends are very helpful when I find myself unable to find a solution to my character's problems. When I ask them what they would do if they were a powerful mage looking for revenge, I get all kinds of inspiring answers. It leads to very long and animated conversations.
I love being a writer, despite the silly problems it generates.
