Life is definitely crazy, balancing work, kids, spouse, ailing parents, etc... but life is what you make it...
What I try to do is simple... Largest rule around our house, first and foremost, leave work at work... Home should be your safe haven, away from it all.
Secondly, your kids are only one young once... spend time with them, play with them, the housework/yardwork, etc will get done somehow...
Thirdly, spouses... take at least 2 nights a month and get a sitter for just you two to go out... albeit out with a group of friends or just the two of, a night out sans kiddos is a MUST. It keeps your sanity...
If you both work, divide the household chores, its only fair. Also, remember, the little things in life can keep you connected to your spouse that don't require much time... a phone call mid day to say "hey, i was just thinking of you and wanted to thank you for going through this thing called life with me" Tape a note to a bathroom mirror that might just say "i love you" little things like that don't take time nor money but speak volumes...
and last but not least, don't beat yourself up if you haven't obtained the perfect balance yet, just keep working at it.. don't roll over and say "this balance shit is too much, i can't and will never be able to make it all work" that is the easy way out...
