Beginning the Novel

So this is it. I'm at the part in the book where I apparently start writing the novel instead of doing lots of character bios, making decisions about the plot, P.O.V., etc. And I'm stalling.
I don't know. I guess I haven't written scenes in so long that it feels difficult now, which is ironic because the only way I knew how to write before was by writing the whole thing out scene-by-scene.
Did you know one of the most common misused words is the word "ironic?" I have no idea if I'm using it correctly up there but, if I'm not, I'm letting you know I know it's supposed to mean something that's similar to what everyone thinks it means, but not exactly.
Back to the novel. I have all of the character bios done and the story has taken shape since. The message/plot started out being one thing years ago, then transformed to reflect events in my life at the time and now it's back to the original message/plot which I personally think is more appropriate. I can get out my feelings on earlier events in a far more... I have no clue. It's just not going to be this book.
Have you ever thought about how ridiculous the English language is? I mean, for example, the word "though." Why was the "ugh" even added. "Tho" is perfectly legible, easier to pronounce, and there isn't another word like it. Not having the "ugh" would certainly make it less likely for sleep deprived college students from mistakenly typing "though" instead of "through." They don't even sound similar and yet they end the same way. You throw in the word "enough" and you really want to say "ugh!"
I don't know why this is becoming such a big deal. Probably because it is a big deal. Stories take time to write which I know very well. I've never finished one. I had twenty-two chapters written for a story freshman year of high school and it wasn't even close to being done. That was just part one.... I really should have kept that thing but I think years later I looked at it like "yeah, this isn't mature enough" but I could have saved it. It was a very different story! At least I haven't seen anything like it yet and considering I wrote that over ten years ago there's been a lot of time for someone else to think of it.
Is there a council we can take the problem with "though?" Because I really think it's about time we change it. Especially with Twitter and text messaging- those three extra letters can cost money!
