I am not the type who is obsessed with perfection. I was once that type, but I re-trained my mind to erase this concept of "perfection" and just take the pain with the pleasure, because this creates the contrast in life and I wouldn't have it any other way.
However, I think that there is
that type of pain that you just embrace, because you know it's worth it, and there is the other type of pain that makes you not enjoy even the pleasurable parts.
I think there is a lack of understanding when it comes to the concept of pain and discomfort. For example, if we take a professional football team's training : a guy who has an athletic body with broad shoulders, powerful legs, well-formed muscles and strong limbs is going to feel a totally different pain than the guy who is incredibly skinny, has weak musculature and fragile bones.
Of course that both of them are going through discomfort, but it would be ridiculous to say that both of them are experiencing the same level of discomfort. At the end of the day, the athletic guy has significantly higher chances to be satisfied with his career than the skinny guy, and it has nothing to do with the fact that he would handle better hard work, it's just that he is more suitable for that type of job. The skinny guy has a higher risk of quitting, simply because
the type of discomfort he experiences is not worth it.
The same type of denial and lack of self-knowledge is happening in Medicine also for many people and then we wonder why are depression and suicide rates so high. All this for what ? Because they don't accept that not everyone is made for Medicine, no matter how much effort is put into it.
I know things in US are harder, because you have crippling debts compared to Europe. Here we have many Medical schools that don't leave students with such high debts.
So obviously I don't want to be a smartass and pretend what I wrote can be applied to everyone, but
for those who aren't burdened by the debt, it's worth to consider it.
I heard from US students that "I swear I wouldn't think twice about quitting Med school if I wouldn't have the debt !" - Well, guess what, here many people don't have any debt and they still don't quit, although they would like it.
The pride and the fear of social judgment doesn't let them quit, it has nothing to do with money.
My father is a cardiologist and he also teaches in Med school. Often times he told me what a shame it is that the quantity of students increases, but the quality of doctors decreases every year. He's saying that he wouldn't want to work with 50% of the students that are in Med school, because most of the time they are nervous, bitter, superficial, confused and robotic.
He said that if they would be more honest with themselves and if they would dare to actually do what they really want to do, they wouldn't be this way - actually, they would leave Med school and he would finally get rid of them

Only the fact that so many of them are so shallow and susceptible to social conditioning that they are willing to go through all this training for some prestige tells a lot about a person.
