Definition of self-efficacy: A person's belief about his or her ability and capacity to accomplish a task or to deal with the challenges of life.
I like the way this word is defined by only my own belief, ability and capacity. I certainly understand the word capacity; but I'm wondering about its link to the word capable. I know I am capable, but have I ever really tested my capacity? It's a good time to think about my believes about myself.
