That's actually a great point and a downside to extra work. Maybe the middle ground would be to do extra work for fun and not bring it up, or just finish work early and work on something altogether separate on the side?
Yes, and the next time a 50-hour task comes up, they'll expect you to do it by tomorrow.
The problem with faking your way into being a 10x rockstar is that expectations grow faster than compensation. The other problem is that if you can't sustain the pace, you're going to burn out and your life will be utter crap.
I'm pretty sure you're supposed to catapult into doing training and speaking stuff, and "leadership" roles that have you writing blog posts and attending meetings all day while taking credit for what your team is doing, after faking your way to a "10x" reputation.
No. Sometimes something just does work out faster, so explain that. Spend a little longer anyway as if something is vastly faster than expectations then perhaps something's been missed. Then when still presenting it faster, explain that it was faster than planned and shouldn't be taken for granted.
