«21 management things I learned at Imgur» (https://medium.com/@gerstenzang/21-management-things-i-learne...) — pretty good. The best and most general, to my mind:
«It’s terribly difficult to manage unmotivated people. Make your job easier and don’t.» ‎· 9000
«You’re more likely to lose by not recognizing your weaknesses than from the presence of weakness» ‎· 9000
«The best way to manage great people is to provide clarity of purpose and regular feedback (which is different than regular direction)» ‎· 9000
«[L]et us pretend that all past success was the result of our situation and not our own hard work or good qualities. We now have a unique opportunity to reduce our dependence on luck through superior performance. There is no cost to this belief except your ego» ‎· 9000
"A personal mantra I’ve found useful is “we were lucky but now is the time to be good.” — офигенно. ‎· liquidgold
