I became a PM last year only months after learning what a PM actually is. I did not have a software or product background, but I did have a significant technical background in the product domain for which I was hired.

I have found the entire experience both incredibly rewarding and incredibly humbling. I've never worked in a position that is so broad - from technical expert to support to tech writer to customer success to management.. every day is different. I do think this sums it up well:

> 14. Be on top of your shit. Until I figure out how to better articulate this, I’ll say it ineloquently as “just be on it.” Know your business, your product, your team, be responsive, communicate relentlessly, make good decisions, own your results, get 1% better every day.

If you're not constantly on top of everything, it becomes chaotic and obvious very quickly.
