There's two parts to this issue. One is being successful by typical worldly standard. The other are emotional scars. Maybe, it's not necessarily feasible for everyone to achieve hoisting themselves from homelessness into a white collar above average paying job. Maybe that's not possible. But this is besides the point.

What is eminently more possible is achieving emotional worthiness. When a person is rejected, however that came to be, this activates a physiological response in them which causes them to perceive scarcity, which wreaks havoc on any number of processes in daily life that, building up, can rip a person down.

What are the antidotes to this response? In my experience, gratitude is a strong antidote, when & where you can find it.
