If you can, start your own business while you're working another job so that your bills get paid. Choose something that you love, so that when you're exhausted when you come home from work, you're actually looking forward to your 3 hours every night that you can apply to your business, either after your kids go to sleep or while they're watching TV or while they're doing their homework, however you can budget your time. Instead of a chore, choose something you love so you absolutely look forward to it.
