Would it surprise you that most people feel insecure in one way or another? Many of us don't know it, some of us do. People hide their insecurities in different ways. The mind is full of self defence mechanisms. Usually these insecurities develop at a young age with our peers through a negative experience. Hence, these insecurities turn us into someone we really are not. It is usually easier to pick up on someone elses insecurities but you may also be aware of these things in yourself. The "not good enough" image is a construct of our imagination. It is a belief about ourselves created by the mind.
Most people are too attached to the past, to what they are familiar with, and therefore, miss opportunities that stand right in front of them. Doors may close, but there are always other unlimited number of doors – new opportunities. The world is full of opportunities, if we could only see them.
This crazy place we call our world we live rewards the people who won't give up and specializes in redemption. It’s usually right when we think things aren’t going to work, right when we are fed up, tired and about to give up – that we are on the brink of our greatest success. Soak in what we are learning, toss out what’s not working and make new attempts with different strategies based on the information we now have about what doesn’t work.
