I don’t think that you should be too concerned with making mistakes, it’s not like you’ll run out of them or anything.
But if you feel anxious, or overwhelmed, you can remind yourself of this one time in 1961; John F Kennedy decided to invade the Bay of Pigs, and failed miserably resulting in the deaths of over 100 men and the loss of $53 million(est.) dollars worth of goods traded to Cuba for American prisoners.
Deind, I’ll bet that even if you tried to ****-up this badly, you couldn’t do it. And JFK was arguably like, one the most successful people of the 20th century. So just remember: everyone messes up.
I wish you the best at school, please don’t have a mental breakdown.
