1. global self-esteem is not a major predictor of anything with the exception of happiness 
Self-esteem is defined here as trait (global) self-esteem in the absence of aversive social experiences. This is a specific type of self-esteem measured on the Rosenberg Self-Esteem Scale (RSES) to detect the overall attitude that we have towards the self.
William James over a century ago said it best when he described this measurement as “a certain average tone of self-feeling which each one of us carries about with him, and which is independent of the objective reasons we may have for satisfaction and discontent” .
Effects of Global Self-Esteem Overstated
Although global self-esteem has been associated with a host of problems – delinquent behaviors, promiscuity, substance abuse, depression, hostility and life satisfaction  – that, for example, educators have attempted to artificially inflate to improve grades to no avail and that our culture seems obsessed with, the social psychologist Dr. Roy Baumeister correctly reminds us that these are just correlations.
Dr. Baumeister bases this on a survey conducted in 2001 of over 15,000 publicized studies on self-esteem, where only primary studies were chosen in order to see the original data. The conclusion is most astounding, and I will quote below but in essence global self-esteem is not that important to much of anything but our overall happiness, which, of course, is significant in its own right .
With the exception of the link to happiness, most of the effects are weak to modest. Self-esteem (global) is thus not a major predictor or cause of almost anything (again, with the possible exception of happiness). 
Perhaps we shouldn’t be surprised with these findings since if you look at the questions from the RSES (see Figure 1), they don’t detect extremes in attitudes and feelings about the self, with the exception of numbers 3, 9 and 10. To me it is obvious that it’s in the extremes of our ego states that we may exhibit detectable behaviors but not from measuring our biased, aggregated opinion towards ourselves.
This does not mean that other forms of self-esteem, say state or specific , can’t have a measurable effect on behaviors; for example, we can feel a state of inferiority after someone disparages us prompting retaliatory measures on our end, but this is state self-esteem. State self-esteem along with self-esteem instability, which underlies the narcissistic trait, is tied to behaviors, but these are more difficult to measure [7, 8 , 13, 26].
Figure 1: Rosenberg Self-Esteem Scale – RSES
I feel that I am a person of worth, at least on an equal plane with others.
I feel that I have a number of good qualities..
All in all, I am inclined to feel that I am a failure.
I am able to do things as well as most other people.
I feel I do not have much to be proud of.
I take a positive attitude toward myself.
On the whole, I am satisfied with myself.
I wish I could have more respect for myself.
I certainly feel useless at times.
At times I think I am no good at all.
