How can having self-efficacy help me? How can having self-efficacy help me?
Basically, I would say that having self-efficacy helps you to be flexible and resilient. It helps you to be able to bounce back from setbacks, to get back on your feet and be able to succeed.
I am using the term "self-efficacy" here to mean the belief that you are capable of being effective -- that you are able to succeed. As the article in the emory.edu link says, self-efficacy is what you believe
about their capabilities to produce designated levels of performance that exercise influence over events that affect their lives
So how is it helpful to have this? Well, we all fail at numerous times in our lives. We all face hardship. So what do you do at those times? If you are not confident in yourself, you are much more likely to give up or to feel that you cannot overcome obstacles in your way. If you have self-efficacy, however, you will have faith in yourself and you will try harder and with more confidence. This will make you more likely to succeed.
To quote once more from the link, you need self-efficacy
because ordinary social realities are strewn with difficulties. They are full of impediments, adversities, setbacks, frustrations, and inequities. People must have a robust sense of personal efficacy to sustain the perseverant effort needed to succeed.
Thinking you can is more than half the battle. If a task is before you and you don't believe you can accomplish it, you probably can't. Self-efficacy is the belief that you can do what is humanly and physically possible for you to do; without it, simple stumbling blocks become insurmountable walls. That's a characteristic which allows you to accomplish great things.
Self-efficacy has to do with believing in yourself. If you don't believe in yourself, then you may not be able to accomplish goals that you have set for yourself. This is why self-efficacy is important. It helps people to believe in themselves and develop self-esteem.
