"will live a successful life without more of an education"
for the beginning, the given options are good.
I don't like much the translations "vida exitosa"/"vida con éxito" wich are literal ones.
I know lots of successful lifes with no education but big effort.
Here I would say something like
"vivir una vida provechosa sin más educación"
I don't really find the proper spanish word...
