How do you rate your value mostly? How do you figure out how much you are worth when it comes to your career? How much should you charge your client? Are you creating quality work for the money? Bear in mind that whenever people spend on you, you are being paid based the supply and demand of what you’re doing.
When you like to spend time with someone, it’s because you’ve measured your return on investment. A high ROI would mean delivering high value in return for a small investment within a short period of time. While a low ROI would naturally mean the reverse.
