Can't use Sublime Text 2 from Mac terminal

Hi, I'm trying to follow the instructions from here.

So I typed the following in terminal:

ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl

Terminal tells me:
ln: /Users/2013/bin/subl: File exists

I then type:
subl --help

And it responds with:
-bash: subl: command not found

I tried a few things before the above steps and I'm not sure if what I tried is causing the above to not work. Here's what I did:

At first I was following the wrong docs and was running this command instead:
ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" ~/bin/subl

I also did this:
mkdir ~/bin

because it was giving me a no such file or directory error- I think it went like this:
/Users/User/bin/subl: No such file or directory

I think I tried all the suggestions here.

I also tried Dustin’s code from here, which was this:

sudo ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/bin/sublime

I'm not sure what else to try. Can anyone help please?
