Self-confidence is the realization that your ability and judgment can make you get the results you want.  It springs from having adept knowledge that you can do something very well and that you can easily learn new things.

Self-confidence is a learned characteristic.  You can achieve it if you let go of your inhibitions and self-doubts, and the only person who stands in the way is yourself.

Here are some ways that can help you achieve self-confidence:

1. Stop comparing yourself with others

Each person is a unique individual who has his own identity and set of talents.  Each has his own capabilities, strengths and weaknesses.

You cannot be separated from the shadow of your own self-doubts if you keep on comparing yourself with other people.  You should be able to identify your strengths and use it to realize your objectives.

Remember that you are a unique person and you have qualities that other people are not gifted with.  You should be able to identify the areas that you excel in and master it for it will surely take you somewhere.

2. Know what you want and where you want to go

Life is not all about living and dying.  It is a gift that you have to do something worthwhile with.  You don't have to squander it by wandering aimlessly through time.  You need a sense of direction where your goals and objectives should be headed for. 

You should classify your goals into short-term and long-term.  Take one at a time, with the smaller ones being taken cared of first.  The achievement of goals should reinforce your self confidence and it will continuously grow as you are able to succeed in bigger ones.  Don't be afraid of failure, for they are always a part of the process.  Fear of failure is an indication of self-doubt.  You will never succeed if you stop trying.
3. Be happy

One of the most apparent characteristics of self-confident people is their happy disposition without regard to the situation at hand.  They always see the positive side of things even if things seem unfortunate in the eyes of others. 

Confident people are happy individuals who have the ability to think outside the box.  They can place themselves on top of the situation and resolve it without getting emotionally involved in the process.  This quality helps to them to make sound decisions.

Self-doubters and less confident people react to the situation differently because they magnify the negative things and blame themselves or others for it.

Self-confidence is energy that comes from within.  It comes from knowing that there's something you can do to get the results you want.  But you have to see the bright side of things in order to be confident that you can do it.
