Ask yourself: is it worth it in the long run? What will be the ultimate cost and benefit? For example, if you’re invited by your co-workers to get drinks after work, but you know it’s your night to cook dinner, you’ll have to decide the cost-benefit of the situation. Benefits: a few drinks, great conversation and a night out on the town. Costs: an upset wife/husband, a $75 tab and loss of personal time with the kids.
