What’s the difference between success and fulfillment?

Successful: adjective, accomplishing an aim or purpose.

Fulfilled: adjective, satisfied or happy because of fully developing one’s abilities or character.

Is it that others may decide if you’re successful but only you decide if you are fulfilled?

If someone asks me to do something, they decide if I have successfully accomplished the task. If I decide that I want to learn to play guitar, whether I’m successful at it or not is up to those that hear me play.

On the other hand, I decide if my chosen task fulfills me. I decide if the job I do is fulfilling. No one can answer the question “Is this fulfilling?” for me.

A relationship, a job, a goal can be successful but unfulfilling, or fulfilling and unsuccessful.

In life, I choose to work toward the feeling of fulfillment. I can choose to feel good about an unsuccessful attempt. I can’t choose if I’m successful.
