This part is lower level, but at my company they always wondered how I mastered the toughest single topic.

When I joined they told me, dont bother learning that, nobody understands it and its very difficult.

I slacked off on the easy stuff and neglected it, I dedicated myself to mastering the one thing nobody else wanted to do.

Now I am lazy and irreplacable.

"Do what nobody else wants to do" is the quote they got out for me for that...
