I agree w/ a healthy self esteem and a lot of confidence. Formal education can do a lot but nowadays more than 30% of the population has a college degree. And not all of those ppl are successful or content w/ the direction their lives are taking. A lot of educated ppl are in dead end jobs, in financial distress, in bad relationships, struggling w preventable emotional issues, etc.
Yes, I think love is necessary for healthy self esteem.
Not trying to minimize the importance of education; but I personally don't know anyone (socially) who hasn't completed high school. So in my little world, a high school diploma is a given. I used to think a college degree and maybe even an advanced degree were all but necessities. But now I see that ppl w/o them can do well...especially if they are White.
