... with the Catholic Church!
What's not to love? She has everything. There is a feast day for every occasion, a patron saint to invoke for intercession from everything to cheese to menstrual cramps. There are even devotions galore to suit every spiritual type and need. You could never bore of Her or lament "I have nothing to do, nothing to read, and no one to pray for". If you do you aren't trying hard enough.
Oh, and She's diverse. There's room enough for every one here; poor and rich alike. Whatever your preference or area of expertise, you will find a place in the Catholic Church.
I know, this may seem like a contradiction to the post below. On the contrary, if anything it illustrates how completely unnecessary it is to tamper and tailor the liturgy of the mass. The Holy Sacrifice of the mass may the pinnacle of our faith, but our faith doesn't stop when we depart the narthex doors. It extends to the outside world and permeates our daily lives. Or at least it should.
I suppose if you regulate your faith to mass attendance only then I can see how you feel it justified to have masses to fit a specific worship style.
But if you are doing your Catholicism right, you can have your spiritual preferences manifested and fed through all the other endless sources the Church has to offer. There are lay groups in each religious order, prayer groups, social justice ministries, and Adoration... just to name a few.
Isn't the Church exciting!? Doesn't it just make you want to invite your non-Catholic friends and family to mass? Or recruit members to Her fold.
There's a reason why I'm called "The Poacher" in the company of friends.
