I appreciate the OP's question and everyone's thoughtful responses.
One thing I've wondered about parenting since about Day 1 is, if I'm doing it right, should it feel good? If I'm a good mom (or at least a good enough mom), should I be having fun & enjoying myself & feeling good?
Because at first I sure as heck didn't. I had a long, difficult labor that left me completely exhausted and then I got a raging breast infection that took 12 weeks to clear up. So for the first 4 months of my DD's life I was basically a complete miserable wreck.
But I was doing "the right things" for her...I was breast feeding in spite of the infection, I was co-sleeping, prioritizing her needs, watching her grow & develop just beautifully. There was certainly joy in seeing her thrive, but it didn't take away my exhaustion & my feelings of being completely overwhelmed by everything.
And now that I'm further along on the journey (DD is 21 months now) and I feel so much better (getting adequate sleep most of the time, for example), I am enjoying myself a lot more. But I wouldn't say the balance of "doing things right" and "enjoying parenting" is quite even. I feel like I get it right 90% of the time, and I truly enjoy it 75% of the time. The other 25% of the time, I'm stressed out or tired or just wishing I could have my own life or at least sit still on the couch in the quiet for 10 minutes or whatever.
I think a lot about my mom, who died 12 years ago. She was an amazing parent, something that I didn't always know or appreciate, but boy do I see it now! And I remember a lot of the wonderful things she did for me, but what I cherish most are the times when I sensed that she was truly happy. I believe that parenting was her biggest joy in life (god knows it wasn't her marriage!) but with 4 kids to take care of and an unsupportive spouse, she was under a lot of stress. And yet she found ways to bring joy not only to us, but she often gave us the sense that making us happy made her truly happy, too. It has always seemed to me the creulest thing that she died before she had a chance to be a grandma, which I think is when you really get to do all the things that are great about parenting with your grand kids, and skip a lot of the hard stuff.
There may be women out there who are not only great parents but who have a blast parenting all the time. But I haven't met them yet.

Fairejour, I hope you're finding some joy in your life. Good luck!
