The skill we each must develop, in order to grow as people and take care of our most important needs and wants, is confidence in ourselves. Be it as a single person, "I am confident in myself all the way," or be it as a group or team, "We are confident in ourselves and our shared ability and responsibility."
I have learned my own self-confidence the hard way. I pushed against shove, and often did so only when push came to shove. Learning to trust yourself and your own intuition and feelings takes effort and time. The best way, that I recommend, is taking on challenges every day. Regardless of the sense in those tasks, we all must challenge our abilities and ideas in order to grow. Just as important, we must do this so that we don't wither and eventually wilt.
