Self-confidence does not happen by accident.

It comes from repeated practice and small successes which build into large successes. With the right commitment and effort, you can build self-confidence in a short period of time and, as you continue with the positive habits, self-confidence will continue to grow.

Self-confidence depends on a combination of good physical health, emotional health and social health. It is hard to feel good about yourself if you hate your physique or constantly have low energy.

Self confidence is attained by clearly having an idea, know how to proceed, motivate the people and maintain self dignity on a problem taken. The behaviour to others also reflect the same.

There are many factors that affect our self-confidence, including our parents, our upbringing, our environment, our beliefs, past failures and successes, society, how other people treat us, the media, and our experiences at large. Research suggests that the beliefs individuals hold about their abilities powerfully influence the ways in which they behave and achieve (see Bandura, 1977, Parajes, 1996, p. 543).

Hi,

Self confidence comes through constant practice, passion, devotion and love for the work. Have you seen a chef confidently handle his utensils with a style signature, which no normal man can do. The chef may have invested several hours to understand and hone his skill to be able to stand out unique.

Thank you Terry Purvis for your answer.

We should be honest, hard working, sincere, with positive thought and keep faith on God - help to get self confidence.

Thank you Tapas Chatterjee for your answer.

Self confidence is attained for a person when one is quite familiar in doing things in exact way and knows how to do and proceed. For this, one has to be confident in what a person is doing.

You must first of all understand what you are doing.

Strive for balance. Like everything else in life, building self-confidence is about maintaining balance. Too little self-confidence can keep you from achieving your goals and feeling good about yourself.

I agree with Terry Purvis

You have to trust for every thing you will do.

By seeing, observing, understanding and by practice, one can stand by oneself, be clear, know the specific purpose of doing things thereby become self confident.

Standing on/ongoing with sincerity, honesty, hard work and with highly focused target.

Believing yourself

Strong will power is one of the most important thing.

Self motivation is very important thing.
