The Lord said to his people: "You are standing at the crossroads. So consider your path. Ask where the old, reliable paths are. Ask where the path is that leads to blessing and follow it. If you do, you will find rest for your souls." - Jeremiah 6:16
To be "at a crossroads" or "at a crossroads" is to be at a stage in one's life when it is necessary to choose a course of action that will affect one's future in significant and irrevocable ways.
Never feel bad for wanting to better yourself! If you have people who are genuinely for you, they will encourage you and motivate you to become a better you.
