Last year, Albert Bandura, a renowned psychologist and giant in the field of education, passed away in his 90s. Bandura is best known for his pioneering work around the idea of self-efficacy—a concept that impacts you everyday and has powerful potential for your writing life as well.

Whether you realize it or not, your self-efficacy guides nearly everything you do. It’s why you feel completely confident as you stroll to the washing machine to do a load of laundry: because you’ve done it before, you know how it works, and you have total faith in your own ability to get the job done well. It’s what causes you to shy away from attempting some of the Olympic gymnasts’ routines in your backyard: because you (most likely!) don’t have the years of experience, the skills, and the proof from past success that you can accomplish them.
