Question for the single readers

Some people are pondering over the principles vs. methods side of parenting. The principles vs. methods discussion (especially in parenting) is a huge thing at RP. Contrary to popular belief, we don't all believe that each family should have 5 kids. Some only make it to 4 and we've come to accept them and their flaws becuase that's what Jesus would do (hahaha).
I'm catching myself wondering, do I fall into this trap as a single person? How would I stay out of that trap as a single person?
Now, I do have some of my own rules, to be quite honest, but I'm not exactly sure if it's quite the same. Three rules that pop into my head immediately are
(1) You must go to morning and evening service
(2) You must give your whole tithe and offering to the church (missionary and Chrstian organization giving falls into "discretionary spending" category)
(3) Wednesday night church is not an option
The second rule I've never thought of as a rule because whenever I've asked older and wiser people, that's what I'm told. I thought that's just how tithing should actually work.
Other rules I have come about by circumstance only. They will change in a new living situation, job, or when I get into a relationship.
Oddly enough, the sermon on Sunday was about this very thing and a warning against hypocrisy. I teared up when the pastor asked "Do you care more about the opinions of others or taking pleasure in God?". Definitely opinions of others. You see because I have no rules (even as a child, there were only two rules in the house "Don't chew gum" and "Don't lie". Silly me, I thought those were actual rules. It wasn't until about 3 years ago that I realized I was living in a fantasy world.) it was like swimming upstream to fit in with the Christian crowd when I came to Covenant. Forming friendships and keeping them proved to be the greatest challenge of my life because I had no rules. I didn't see why people should have them. Besides, even in Christian circles I heard about legalism and that it was bad.
However, I entered the Christian world and boundaries between the genders is a huge thing. (I really wished someone had warned me of that before I came to Covenant. I had no idea what I was getting myself into.) I learned that you can't just go up to guys and put your arm on their shoulder. Slugging them is out of the question. Calling guys as or more frequently than girls is just not kosher.
Frustration can't even begin to describe how I felt when I tried to fit in with other Christians. Some of them didn't like rules. Some of the thought rules earned you sanctification points. Some played by the book and didn't let me read out of the same book. I wanted to scream. I think I did a few times.
This is why I like Donald Miller. No rules. He hiked to the bottom of the Grand Canyon on two days notice. He helped with a tent about Christianity on one of the most liberal campuses in the United States. He is part of a church that wants to teach young people to garden so they can learn more about God. He cares about young boys without fathers.
Lately I've tried forming rules and it just doesn't work. Being responsible is one thing, I do need help with that, but I can't function on a list with 10 steps to financial success. As much as it pains Dale Carnegie people, I can give someone a sincere compliment without saying their name first. I know I'll find a spouse some day, but it won't be from my 29 demension profile on e-harmony.
Maybe, by the grace of God, this isn't something I struggle with. There are many things that need to repaired in my soul, but maybe this isn't one of them.
