Releasing the Guilt of Charging What You’re Worth

I can still remember sitting at my desk one night after another twelve-hour day, eyes burning from staring at my laptop for so long. I was revising a client’s brand strategy deck. The number of edits the deck had undergone exceeded our initial agreement, but I didn’t have the courage to decline. When the project finally ended, they thanked me warmly but never paid the final balance. I reached out multiple times, but when I got no response, I just let it go and didn't even chase the money. I thought about blasting them online, but what good would that do? I honestly just wanted to move on.
