Random thoughts: too iron-teeth in my work?

There is plenty of well-intended advices at my work. Being new to my role, many told me I need to be firm and is "too nice". My boss told me I didn't communicate enough.

The weird thing is: 

1) when I am reflecting how I can do my job better, there were many things which I thought I could have do better, but no one said anything about those,except one. He is a officer from my department.

2) those which are my core values, I do not think i will shift anytime, many have a opinion. LOL

The first thing which I find irksome is "calculative". I do not believe in taking someone for a ride, but I do think we can never be "fair" in workload. 

Having to manage that part is rather "bo Liao" and I felt my limited energy can be better served somewhere.

I made some arrangements on my own so that my staff who got less "rest time" will be "compensated" before they start their work in the afternoon. 

I was called in to my bosses "Twice" to explain why I make those arrangements and that I am making things difficult for my fellow colleague who did not make those arrangements. I explained and I said I understand where they are coming from, but seek their understanding in my decision. Inside me, I am screaming " BULLSHIT, that U did not care enough for your people is your bloody business because they are not under my charge, instead of asking me to lower my standards u should bloody reflect yourself"

I realised many, including, myself, seriously need to go to the lake and see their reflections, and if they are ugly, should put their head into the water and cool Themselves off. 

I am guided by this simple principle, I am not dogmatic in my approach as long as I can get past on this simple value.

First,

I am

Most importantly a human, I tried to be kind whatever I could as long as my kindness do not lead to

Negative consequences. And no, that my way of doing makes people compare unrealistically is your bloody problem

Next, I am a teacher, then a HOD. As long as the heart is with teaching and pupils, I can forgive all. And I hope my staff forgive my lack of adminstration competency too. 

Seriously, I am rather iron-teeth when those two principles are concerned. I wondered aloud if one day I am thrusted to the private world, will I survive?

Let's justs allow me to indulge and live with those 2 values I hold dear, and if I cannot survive here, then let me trade those useless values for the next pay cheque.

Don't tried to persuade me now. I find it full of shit when u claim u are trying to teach me when I felt u are hardly really more competent.
