Lately my inspiration is flagging. I told him to establish set business hours for himself, when his wife and kids understood that he was working, and not to be disturbed unless there was an emergency that needs his attention. Not even close. But I keep trying. Then I suggested to him that this problem often happens with fledgling businesses like his which are just starting and not making much money yet.
Frequent interruptions can also be a sign of family resentment brewing.
Then, the couple is off on a vicious cycle. He blames the lack of concentrated time for his business on not pulling in the income. To this advice, my friend pointed out that he was indeed making money and that couldn't possibly be the source of the problem. And so, I suggest another idea to consider. It takes two to play this game.
