Your first job won’t define you. It’ll teach you how to show up, and that’s enough.

The early jobs are not a statement about your ceiling. What they install is more basic and more durable: being somewhere at a set time, finishing a shift you did not want to finish, staying civil to someone who is not. Those are learned by repetition, not by reading, and almost everything later depends on them.

Give yourself credit for the unglamorous part rather than waiting for the job to be impressive. Track how many shifts you have worked without being late. That is a skill, and plenty of people never acquire it.
