Ugh, I need one too.
I've started 2 novels, 1 series and I can't ebb my distractions from it.

It's natural, everyone gets bored of things, if you think that writing it would be a good thing to do (i.e. someone's going to read it/it's going to get published) then you just have to force yourself to persevere.

happens to me all the time -.-'

usually it happens when i have a lot of free time. it helps me to set aside a specific time and amount of time to work on it. once i get into it i usually go past the designated time anway

I'm exactly the same way. I've started several projects, but have a hard time finishing them. But, there is a way to break the cycle. Writing is a lot fun, but requires a certain amount of discipline if you want to finish a long piece.

Do you have a routine? If you only write when the mood strikes you, I suggest setting apart a time where you focus on nothing but writing. I thought this would be difficult, since I couldn't see myself forcing the creative flow -- but it helps. Even if you can't get anything out, just write. That's the point. You can always edit later. Eventually, I saw myself producing more and more after each session. I had to learn this, as I'm very hard on my own work. Good luck!

know what your story is about and give it a fitting ending or any ending. when you go back to read it cold you will know where to go with it.

Oh! Another tip: write an outline. It'll keep your pace, and if you don't know what to write next, take a look at your notes. This helps a lot if you have a confusing or "busy" plot.

pursuing is hard.
but life is about pursuing.
life is hard.
life is pursuing.

Write a story about a topic which you know lots about. When I do, I find that when I know what I am doing, I get it finished early, and it makes sense.
