One of the hallmarks of confidence is being sure about your abilities and that those abilities will ensure a positive outcome. The definition of self-confidence for me is what extraordinary things you can do when you believe in yourself. Confident people have a strong self-esteem with a realistic respect for themselves and their good attributes.
If you don't have self confidence you're more likely to see other people as enemies or competitors.

By doing so you reinforce positive behaviors, acknowledging your accomplishments building your confidence along the way. When persistence is coupled with confidence, your goals seem more attainable improving the likelihood of success.
All you need is to assess your abilities and compare it's circumstances in two ways; First when you are a self-confident person and second when you are a person that lacks self-confidence.
When you will yourself to carry yourself with confidence, even when you aren’t feeling that way, you send signals with your body that failure is not an option.

People with low self esteem have difficulty believing that they are unconditionally loved and accepted by their partners.
