Eeeh, why not do all of them?
Do the first one on the list, then the next one, when you completed it do the next one... And so on until you've done all of them and you get the Quest Skillcape
You could do a few quests in 1 day if you use a walkthrough, RuneHQ for example.
There was a time when I loved to quest. I thought doing quests was so fun and I loved the stories that came with them. But that time has passed.....
Perhaps if I had lots more free time (because I don't like having to log out in the middle of a quest, like to finish it in one go) and got into Runescape again like I used to be, then I would find them entertaining again.
