Many people know how to be confident because they choose to be confident. You may know some people who appear to have been born confident, but confidence is a state of mind, not an inherent trait.
People tend to think that being confident is a direct result of feeling good about yourself when, really, it is more complex than that.
Happiness – when one comes across this word, the first image that pops up in mind is that of a very cheerful person who is always merry and has got no problems in life. We complain that fate is so partial in matters of whom she bequeaths her good luck upon, and that we are never the chosen ones. This is as good as complaining that the glass is not full when the glass is half full. The truth is, what matters is not how lucky we are, or how much are we bestowed with, but how we look at things. If we are able to take everything in our stride, then there is absolutely nothing that can take away our happiness.
