From the few times I tried, it's very difficult to look back on my matches without experiencing the negative. That's why I prefer keeping them out of sight and out of mind, because for me, with criticism always comes insults.
Unless I really trust someone, I seldom save my replays to share for the sake of improvement. And I don't trust a lot of people. The article was nonetheless riveting.
This is very sad. I can fully endorse that saving and reviewing replays and previous matches is one of the best ways to improve (and yes I cringe at my older matches every time I watch them, but never regret uploading them). What do you think is the first thing I do when I get home from a tournament? I rewatch the stream and look at every mistake I made. And yes, EVERYONE, makes mistakes.
