In the years past a lot of people on this forum seem to be against letting their guard down in regards to working for a company. While I agree you should learn new things, the question still stands, what's wrong with going through the motions and grinding daily. It seems to me a big part of working and sustain in an environment is treating your work effort / experience as a marathon. Instead of going 100%, dropping back to 85% and sustaining seems to be a better strategy.
Is this something I should of realized a lot sooner?

Thoughts on this concept? I don't suspect it will go over well since most people on this forum are ambitious (I think we all are to a certain degree).
