Half of the motivation one gets at their teenage age fade off when they get older. Just as you wrote, you will have to learn to stay motivated yourself because no one go send you.

I spoke with some kids a few days ago and the were scared to pursue a career choice for a trivial reason. I knew they were lucky to be young to have someone motivate them ALWAYS. At my age, you hear these things once in a while so you've got to be strong yourself. 😅
