Well, then, by your OWN metric, you sure haven't learned how to keep up.
I trade for myself. I worked full time in a distribution warehouse till I got it off the ground. When I wasnt running political campaigns from the city to congressional level, a little truck farm operation on the side till gas prices ate up the profts, and a bit of consulting here and there for some added-value ag projects. I have worked 80 to 90 hours a week for oh, about 10+ years.
So, naturally, after all that time under the glass carpet, and on the outside looking in at people who work only 45-50 hours a week, with regular vacations, you're understandably a little bitter.
You know, you'd have done far better, and will continue to do better, when talking to managers, to emphasize your STRENGTHS and EXPERIENCE, and how they play into your client's needs. Telling a manager you're going to take their job within a year or two only works in the comic strips.
If you look promising, sooner or later they'll slot you for a management role, because despite all appearances, GOOD managers (ones who help the company long term, instead of just building an expensive useless personal empire) are *very* hard to find.
And the best ones act as a blocking fullback for the people under them: who then stay with the company and go the extra mile even before being asked.
Cheers!
I...work...for...myself.
Do I need to say it slower?
