What is the best management advice you've been given?

I wasn't intending on such a deep topic...just generally curious to what advice people had been given that they found useful.
Now, I read this article and have bookmarked the site for further reference.
Along these lines, one book my (civilian, non-military background) VP recommended was "Extreme Ownership" written by Navy Seal Officers/trainers. That book was a hard look at leadership and it's purpose in the business world. Highly recommend.

1st Lt (Join to see) - The more you read, see and experience, the more you want to know. I would say, simply two things... focus on your people 1st, and focus on what you can control.

Agreed. I believe that micromanagement is consciously/subconsciously communicating that a manager doesn't trust the employee's decisions.
My goal is to empower. My goal is to micromanage only when needed until the person can be independent. If they can't, I need a new player for the team.
Do you have an example of mentoring you mentioned?

1st Lt (Join to see) - We made changes to the baseline via documentation called "Support Requirements (SRs)" These were paper documents that would describe the change, cost/resources, risk, timeline, etc. These SRs were pitched at a Control Panel meeting where they would be approved, disapproved, or placed on hold. Eventually, all of the Support Requirement paperwork was incorporated into a Configuration Management (CM) Database. When the database was up and running, we had 10,000 SR paper records that were not online. My boss was against the idea and wanted to toss these old records. I won the argument that these old records needed to be entered into the database for configuration management control and records management. I had two people that were assisting with this effort. One created a tracking database for these historical records, and the other came up with a system to scan these SRs into our CM database. I let both develop their own processes and just provided the basic requirements. I scanned my share of these old SRs into the system in what turned out to be a tedious process, but necessary to preserve historical records. Once this task was completed we put the old paper records in the shred bins.

Can you elaborate on what you consider the best management advice you've been given?

PRP is a combination of advice I have received over the years, I wrote a paper on it and give lecturers. I posted it as a command post on RP also. https://www.rallypoint.com/command-post/leadership-and-the-prp-program

1st Lt (Join to see) - Let me know what you think about my BMPs, while I have gotten a good reception on my presentations to industry I have not received a lot of feedback on RP and thus stopped writing the series. I think my next one was going to be on time management, and update to the 10 Min manger to an extent.

You manage things, you lead people. First heard that from RADM Grace Hopper.

MCPO Roger Collins - Roger... But, it is a matter of perspective. Leaders definitely manage things, but not all managers are leaders. Hence, focus on being a leader first.

And vice versa, there are senior officers and enlisted on here that have indicated problems managing their own finances and personal affairs. If you are to excel, most are critical to your military and civilian success. BTW, I have to go with Grace Hopper, one of my personal heroes.

MCPO Roger Collins - all good points. This has always been a facinating discussion to me... leadership, Managment, and leadership vs management. It is interesting to me, many don't understand the differencs or the similarlites. Take where I work now,,, school administrators, which are really not leaders as you and I would understand, have standards like we we teachers do. There standards are called Missouri Leader Standards, which makes me chuckle, as most are not leaders in the sense the Army, or likely the Navy would envision.
