I mean, Eighteen years old is the age of consent in Europe and you can go anywhere and do anything you like. In America, it is dumb. At eighteen you should be able to do anything that you like, except get married.
By the age of 9 or 10, I knew that I had to cut my own cloth and make my own way.
So though there are many things I would have done differently, I submit to God's sovereignty and His purpose in my life and I thank Him that He brought me the way He brought me and gave me what He gave me when He thought I could handle it.
