You've got to be kidding me
Really? From my perspective, no way in hell I'd trade UP(?), especially if my financial boat was in reasonable order and I was as close as you are.
Why, because it isn't really a trade up and 30% in no way reflects the amount of stress, effort and hours that you will be required to work. It's not a reasonable financial trade, in my opinion. Let's say you ONLY add 15% more hours/stress. At time and one-half since you're already working more than 40, it's 22%+ already. And what's worse, 15% more effort is not even close to their expectations. I can guarantee that. The profit motive is insatiable and as an exempt employee your extra hours are basically free.
I'd estimate that my management jobs usually involved at least 33% more effort/stress/hours than the people that worked for me, including engineers and technical staff. Most of my manager peers work 40-50% more hours in their positions. They are making less than most of our administrative staff in $/hr. It's easy to do, the peer pressure, goal setting and expectations will drive you to do so. That's not even talking about the "fun" you'll have in motivating your disgruntled employees.
My recommendation is to be smart, fly under the radar, coast into retirement, take up another hobby, lose some weight, take up a different exercise routine, just do anything else; please don't fall into the ego or "interesting/challenging" work trap. Remember, it's all about dollars per hour. In my opinion, if you don't remember that point, you are going to be very, very sorry.
