My #1 tool for stress relief in Corporate America was having a fit body.
A fit body meant that no boss could ever slander me without my mere presence contradicting any narrative he could concoct.
A fit body meant chance after chance to succeed. Get out of jail card after get out of jail card so that I would ALWAYS EVENTUALLY succeed in any role that I had.
Your employee metrics only matter within your existing company. But if you want a real pay raise, you have to interview externally. And your body will either confirm or refute what your resume claims you can do.
So if you want to hedge your risk, be fit. If you want to multiply your reward, get fit. If you want to have more options in life, be fit.
There is really no downside to getting fit.
