Why are people bored?

I am on level 12861. I play on windows I do not use boosters although I do have a few (about 300 or more of all boosters except the party boosters) I like the challenge of completing a level sometimes it may take me a few hours and using all my lives or a day or 2 but is fun to me to complete. I usually finish before the new levels come out. I am never bored. Having 20 lives is also a challenge to me but I most of the time never use all of them. YES I am showing off. Lol.
