How do you overcome fear and doubt?"it's weakness that breeds fear, and fear breeds mistrust" MAHATMA GANDHI
Human progress is either by individual excellence, or by by building social capital.
Individual human excellence is generally achieved by uncluttered mind, a mind unpolluted by unnecessary thoughts, productive thoughts, not by unprogressive or regressive thoughts. More the number of these type of thoughts, the more regressive is the thinking, and greater is space of mind is occupied by such thinkings. In such case the person is not able to make any investment of thinking, rather he or she keeps of taking guards to save himself/herself make them safe, secure. The greater the number of guards the more distanced the person makes from fellow people. Under such a circumstance, the other person takes a guard too. Thus it inhibits social capital, the person ultimately does all the work himself, his specialisation gets lost, his ability to utilise his talent also gets lost and becomes very very general And alone.
In in any pursuit of excellence, risks are involved, innovation is involved, association is involved, and a fresh thinking is involved. Moving ahead means some mistakes will occur, then the mistakes are to be managed, through a flexible approach....all this requires courage, stooping to learn, shedding ego but always maintaining self esteem.
A weak mind never thinks of stooping to learn, a weak mind never thinks of association, a weak mind never thinks of innovation, they only go as far as moving on established beaten tracks because of the fear of losing themselves, losing their so called identity. Such a fear of preventing association building, preventing synergy to form social capital, isolates the person intellectually, prevents the flow of fresh ideas, and makes it very inimical of any progressive farsighted growth. The person then withdraws into his/her own cocoon and sees everything threatening him, everything better than him/her everything with doubts....
Doubts can never be the basis of any relationship, can never be the basis of innovation, never be the basis of any progress. Doubt is a sign of weak mind, reflective of fearful thinking. True Purusharth is moving ahead, making mistakes, learning from mistakes, improving that mistake, and thus innovating, forging greater understanding and bonding.
