How to Get It Done; question about goal

Hi. I’ve decided to work through this booklet, and the advice is to pick a goal that can be accomplished in 30 days.

My goal is to get a full-time job making $70,000. Unlike a goal of losing a certain amount of weight or having a chapter of a book written, this goal involves the participation of another person, and I can’t control whether someone hires me.

Is this type of goal useful to use as a 30-day goal?
