Man what the hell

This may be the hardest time for me because I have to choose between science and commerce stream and I don’t know what to do or choose from. If science there is plenty of field to choose from if commerce you will have a straight line so I am really confused. This is just a part of life that I am confused I don’t know how much I will be confused when I have to choose between and make correct decision between many things that lay ahead me.
