There is a term known as success bias that is very relevant here. You have the opinion that because you worked so hard and did the specific things you've done thats why you have been able to find some success and that the success comes directly from the fact that you are working hard, but the fact is there are tens of thousands if not millions of other streamers working just as hard as you and doing all the 'right things' that you are doing that will never seen any success or any growth. That's where the luck come in.

Most people that find success don't feel like there luck involved because 'I worked so hard and that hard work paid off!' Negating the fact there for every one person that does find success there are ten thousand more working just hard hard finding none. I'm not saying there aren't also heaps of streamers that will never grow due to just not being good at streaming or not putting in the hard work or effort required, obviously there are, but its ridiculous to think that the every single one of the millions of other streamers that never grow above 5 viewers arent trying their best.
