Like a PP said, determine how my day is on my own. If he's in a good mood, I'm in a good mood. If he's cranky, I'm cranky. His mood is pretty much determined by how well he's slept, which is sooo inconsistant.
If you can't do it with a baby, then I don't do it. His granny came round last week so I could go to slimming world, that's the only time I've not had with him this week.
I've not done any exercise for months, that's what I'm currently struggling with. I used to go to the gym 3 times a week. If I do have a window now, it's literally my last priority. On the plus side, he's good in cafes, so plenty of tea and cake :).
I tried baby cinema, it was a nightmare now he's crawling. I spent most of it sat at the front, chasing around after him and fending off the 'big kids'.
I've not been further from home than 4hrs since he was born because he's a nightmare to travel with (a 3hr journey took 6hrs last month). We've had a couple of long weekends away, but not a holiday yet.
On the occasion I see childfree friends that I share a hobby with, I find it difficult not talking constantly about him. When I go out with my husband without him, I find it difficult not talking constantly about him (you get the picture). Your world revolves so heavily around his needs, it's your top priority (as above, his mood heavily effects your mood, so it's in your interests to anticipate his every need).
My husband is working long hours at the moment, so I'm housebound once DS goes to bed. Thank heavens for just eat!
But his little smile and the cuddles do make it all worth it. Plus watching him learn new things.
Things I don't struggle with (although he's only 9months):
Having a wee/shower solo
Leaving the house without an hour's preparation (this morning I went out armed with - shock horror - just a nappy, sling and the car keys)
Eating my own food
Drinking tea how I like it (lukewarm, luckily)
At the moment, sleeping (but this is just a phase, it'll go downhill again, I'm sure)
