If you go through life not ever taking any bs, you definitely will not be able to hold a job. Or function in general really.
This is a dumb take. A “gifted” kid is literally one who doesn’t have to try as hard as the other kids. Busting your ass comes later once you age out of grade school and have to develop personal discipline and systems and that is where most “gifted” kids fail because excelling in education has been so easy for them so far.
