The more respect you demand from people, the more they will disrespect you. Your have to earn the respect. Give respect to gain respect. Don't think you will get that respect simply because your in a certain (superior) position.
The more brittle and unflexible you are, the more people will try to break you. Try to show understanding and flexibility to other peoples needs and people will then start becoming more easier to work with, and to mould into what you need.
The more you try to talk your way out of a situation rather than just saying it how it is, the more people will think your being dishonest and a liar. Just tell it how it is and if its because you failed at providing, then say so and people will respect you for your honesty at least. Otherwise, you will end up being a constant disapointment for so many people, time and time again.
The more lack of communication you have with others, the more problems you will face with them. Dont think you can just decide things on your own and expect everyone to be ok with it. Esspecially when your trying to decide on things you dont completely understand. One meeting/or short conversation with everyone is all it takes, in order to get everyones point of view, have trust in them that they also know what they are doing and then base your decisions on this, your still the decision maker, however it shows that you actualy care about other peoples input = Respect. Good communication is key, in any kind of relationship, this is most important. And it will prevent so much future hassle of people apposing your decisions and then things need to be changed yet again. A bit of communication can go a long way.
The more inconsistent you are, the more people will get frustrated with you and not trust you.
Be consistent. People dont tolerate inconsistancy and constant changes. And things are best gained when it is gained through consistancy = organised = some thought has been put into it = trust
The more you think of your own goals, the more further away from them you will become. Everyone involved has goals, its good to remember that, and the more you work towards helping people reach their goals (either it be staff/students/spouse/children/family/friends), the quicker you find yourself reaching your own goals - when your putting others first then surely Allah will give you barakah in everything.
The more sure of yourself you are, the more others will doubt you. Always doubt yourself, dont think your always right, and dont be so arrogant to think that other people are always wrong. Its a noble thing to admit your wrong and to always worry about your intentions and sincerity. Dont allow arrogance to get the better of you.
Lastly, learn from your mistakes. You failed with the last person, or the last situation, so try not to make the same mistakes with the next ones. Because when there is a consistent pattern, your reputation will then start to fail you aswel.
I dont think this is any kind of wisdom, its just pure logic, and it amazes me how some people fail realise it.
