Some people enjoy running after a ball (football), some people get a kick out of lifting heavy things (gym), some people get excited about a new season of big brother,etc, and some like to work hard and occasionally long (me). Working 80-90hours per week is fine for a certain period, but not all the time (not for me at least). It can even give me a certain kick after successfully accomplishing the goal. Working 40-50hours per week ? Fine, if that gets the job done (efficiency, learn to say No, plan, delegate, etc). And once in a while I look around me and see that I could potentially earn the same (or more) money with a role in the industry. But guess what ? I would get bored. And when I get bored I will be grumpy at work and even in my personal life.I like the roller coaster rides with different deadlines, different clients, different problems (industry people hate them, i love problems). And the money ? It's good, but will it ever be enough ? Money is, and will never be, a satisfier.Have fun watching Big Brother, collecting stamps, reading classic novels, learning a language, beefing up at the gym or getting plastered. I'll skip those and do something I like.
