Find a site that lets me add more than 43 things to my list

I am really annoyed that I can only have 43 things on my list. I want to be able to freely add things to it so I don’t forget to do them. It’s stupid having to limit your life ambitions to 43 things.
I know it’s contradicting the name of the website but you guys should change it to 1000043Things!
I’m 16 & need to have more than 43 Things to accomplish before I die! (I know I should really start working on my list so I can add more but for a lot of mine I know they won’t happen for a long time and others (like read more books) are longterm. I don’t want to read 3 books in a few weeks & then mark it as done!).
