At what age should one enter seminary?
Can I enter seminary directly after high school? Can I enter quite old, after a long professional experience?
The question of the age for entering the seminary depends on one’s personal journey, and there is no “ideal” age. The first criterium is, evidently, the will of God. Does he want me to become a priest? In that case, there is no need to hesitate.
However, some objective circumstances have to be considered.
