With a puppy, you won't have a 'normal' life for quite some time. As for other things to do with him, I don't know if this'll help you or not, but here are a couple of things I did (mine's 1 now, and we still play these):
From the day we brought him home, we started with sit, stay, down...just keeping it simple and a few minutes at a time. Around 12-14(?) weeks, we started playing 'find it', and 'hide 'n seek'. Labs are used as service dogs, search/rescue, etc., so I wanted to go with his natural instincts, as well as mentally stimulate him.
Hub would hold him, I'd show him a bone, toy, etc., name it, then hide it (somewhere easy at first, in the same room, then progressively harder, in other rooms). I'd ask him to find it, and gave TONS of praise when he did. We also play 'hide 'n seek'; again someone holding him, I hid, then gave a whistle, and he'd find me (easy at first, then harder). TONS of praise again...GOOD BOY! GOOD FIND!
Now at 1, I just say 'get up here', and slap my hand on a bed. He jumps on the bed, I ask if he's ready, and he knows what we're gonna play. He stays, I hide, give a whistle, and his tail's a waggin' as he searches the house for me. You can play these outside too.
It keeps him mentally stimulated, is loads of fun, he learned commands using play (this helped him learn stay), he learned the names of things and to differentiate among them, and it tires him out.....and when he goes to sleep, you can get things done.
