Sacrifice and Obedience

So I've been thinking lately, what's the relationship between sacrifice and obedience?

My whole life, I'd kind of been bothered by the way people used the word sacrifice i.e. I sacrifice wearing modest clothes for God.

To me, that seems to not quite fit the word. Is it a sacrifice to not drink alcohol? Because it seems like, that's just being obedient.

I believe the words are very closely related principles. When we are obedient, sometimes it may be hard. But choosing to keep the commandments is a choice to be obedient. It seems ill fitting to say, I'm choosing to sacrifice. Maybe just a tad ungrateful...

What then is sacrifice? I thought of times when I felt I sacrificed. I feel like it was making a more selfless choice in a decision where there wasn't really a right or wrong. Commandments weren't involved. For example, I chose to quit a job I adored so I could go back to working full time in order to provide insurance and a better income for my soon-to-be family of two. That was hard. There wasn't black and white answer, but choosing to quit to help my family was a better choice and felt like a sacrifice. 

Any thoughts? What is sacrifice? How does it relate to obedience?

At risk of being too cheesy...

The following post is being made at the risk of being just too cheesy. Reader discretion is advised.

So planning a wedding, buying a house, working full time, making a budget... it's stressful business. And those days are always bound to come, you know, the ones where you freak out because you have this huge decision looming over you, and all the sudden it hits you? Those ones. I was having one of those days. I was wide eyed and quiet all day wondering how on earth anyone survives in this world. There just isn't enough to even scrimp by on anymore. So I panicked. 

I called my sister in law and my mom. I talked to all the ladies at work. I tried to get some reassurance that I wouldn't just keel over as soon as I was on my own with a husband in tow. But my pulse was still racing. Nothing was helping. I was flapping my gums a mile a minute saying everything that was scaring me that day.

I made it home. I was still fidgety. Tom was coming up to do another walk through on a condo we were thinking about buying. He rang the doorbell. I opened the door, and there he was. With, I kid you not, a big rainbow above his shoulder. He hugged me right there, and it was like everything I had worried about that day didn't matter anymore. 

It was honestly one of the most beautiful moments of my life. An ironic twist to the day, and so perfect.

Cheesy, right? I'm not apologizing. You'd been warned.
