Also in my 30s, with a full (full!!) time career and daughter. Here's what works for me.
TACTICS! Not only do I use Chess.com Tactics or ChessTempo during my lunch hour, I also purchased TacticsTime.com's Chessbase database of tactics. Once a week I go through them, any I get wrong I print up and put them on a stack of note cards, then I leave the note cards in my brief case. In spare moments I pull out those flash cards and go through them.
This old school technique helps immensely and you'll find you have more spare moments in your day then you'd think.
I would steer clear of complex books on theory and positional awareness. They are great for enjoyment and learning, but you want rapid feedback and easy to digest materials, tactics fit this perfectly.
Lastly, I would commit to playing one game against a live or computer opponent each evening after the kids go to bed. It's a great way to stay fresh and creates an enjoyable end of day ritual.
Good Luck!

Hello. I would like to hear your advice on ways to improve a player like myself. I am rated around 1300. I am 30, have two kids, a full time job and night school. My time for chess is limited to probably 30 minutes per day at best.
I read Bobby Fischer Teaches Chess and thought it was terrific (easy to take a few minutes at a time, and no chessboard required, which is helpful with small kids around). I also read Seirawan's first three books and thought they were OK. Recently discovered Chesstempo.com and think it will be helpful.
Local chess friends have recommended Nimzowitch My System and Susan Polgar's tactics book.
What tools, books, etc. would you recommend for me? Keep in mind I'm looking for something I can use quickly and set down easily and will generate some improvement in my chess.
Thanks in advance for your feedback.
