Time and time again when researchers have tried to figure out what makes people happy they have come to the same conclusion: personal relationships make the biggest difference. If we valued our happiness over money (as many of us claim to) we would do everything we could to spend time with friends and family and not worry so much about putting in extra time at work. When you look back on your life, you won’t reflect on the time you spent at work; you will remember family dinners, great vacations, romantic dinners, and your wedding. Prioritize people over your career.
