Voice training is hard, and you do seem to be harsher on yourself than you strictly should be - which makes sense because of how dysphoric your voice makes you feel, and voice training does ask you to listen to it and pay attention to it.
Some of it is "simple" but if youve never done it... it aint. Like raising your soft palette? Is a legitimately weird hard thing to do. But it helps with voice. Some is actually not difficult per se, like putting your tongue up behind your teeth and taking up more space in your mouth in general but it takes concious effort at first which can be a bummer (eventually i swear it starts becoming automatic)

I loved it! Fun road trip buddy movie about the power of friendship. Andy Weir 2010s style writing choices weren't super distracting. Ryan Gosling looked hot af, I loved the nerdy thing.
