This is inevitable actually since once the person feels his insignificance, he tends to isolate himself and build a word where he is best understood. He will find his comfort zones, which often led to situations that are convenient for him. These zones may not necessarily help him grow and recover from too low self esteem yet these will cerate environments where he is safe from critical eyes. You see, improving self confidence is just a matter of becoming mature. If you will become complacent with the idea of setting back to lack of achievement and recognition then you will fail to comprehend that life is more than mediocre living. Everyone can improve self confidence regardless of how we were in the past. Normally when we set out to do something we tend to over calculate things and plan to achieve things beyond our present reach. This, we say, would encourage us to work double time. But the point we are missing is that once we fail our expectations and the expectations of the crowd that is watching us, we will be discouraged to try things again. We were all born entitled with achievements and successes. The Universe is too good for us that she took time to secure everything that we would need to soar. Don't waste this very opportunity by putting loads in your back so you would be delimited and thus, incapable of flying. Be like an eagle who has unearthed himself from the mud of being a chicken. Instead, he would have to endure self-sabotaging behaviors and decisions that are manifested through low self confidence. These things would then recreate other ways that lead to difficulties of maintaining relationships, struggles with self-harming acts and tendencies of giving up things. Unless you want a child to suffer a life of miseries, you must be conscious of how you handle him, the things you are making him believe and the acts that you intend him to see. With lack of poor models or lack of encouragement from those we have learned to associate respect and trust on, it would be likely that our maturity would be marked by ambiguity of self image. We know for a fact that parents only act according to what they deem appropriate or best for their children.
