Young people should have the ambition to reach the very summit.
Tips
history
From Du Fu 杜甫's 《望岳》 (Tang dynasty), gazing at Mount Tai: ‘会当凌绝顶，一览众山小。’ (I shall climb to the utmost peak and see at a glance how small the other mountains are.) Written when Du Fu was still young, it is his most iconic line of youthful ambition.
usage
会当 here is classical for ‘must / shall certainly’, not the modern ‘know how to’. 凌 = to rise over, mount.
