I hope your dream of getting married to a white woman comes to reality, and about your dream to be an auto mech, it could still be possible, I understand challenges are paramount to occur in our lives and if you have found a new path that you see success very easily with much obstacles I advise you to go for it because sometimes those childhood dreams are meant to be dreams because we never knew the effort and the challenge life will present to us as we try to achieve those dreams.
