You can't just drop everything, i definitely advise you to start a career. Yes the signs of the end times are upon us but you have to remember none of us really know when Matthew 24:36 '' But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only'' Definitely pray about the things you're concerned about and you should have no reason to worry as long as you trust in God. Take it easy man,
In the meantime I advise you to try your best to follow God and live a prosperous life.
