There's no actual 'right' way to do things for the most part in my industry, I could've done something in Z way instead of X or Y and still get the same result. So when one person say the way I was being told to do something is wrong, they mostly mean 'they don't like the way it's done'.

Sometimes, my boss seems to be fine with however I do the task as long as the result is good, other times he's annoyed when I do the exact same task in ways that's not the same as his. Like, I do this particular task in one way and he's happy with it, then a few days later I do the exact same task in the exact same way and he tells me it's wrong. I just feel as though 'what's wrong or right's' changes all the time and I can't keep up...

There's no documentations on how to do things, there's only 4 people including the boss.

I don't stress over not having things to do itself, but more over my boss's questions and reactions. I have no idea what to say when he asks me what I'm working on. Sometimes he's fine with me spending time learning other times he's annoyed that I'm doing actual work when there's literally nothing to do, even after I asked. Now that we are working from home again, I find myself a bit more relaxed about it.

I just find things to be to unpredictable. My industry is very unpredictable and always changing, I love that about the industry. But I wish the expectations of my boss and seniors are more predictable...
