As an amateur programmer and a part-time freelancer, I didn't have a slightest clue about the value of my work. It was only 5-6 years back when I gladly did small gigs on Want-to-Hire forums for tens of dollars.<p>One particular gig was about scrapping data from a car sales website which I completed for $30 (should have cost at least 10x). The client discussed about the possibility of converting the phone numbers, which were obfuscated as plain images, to plain text. Without ado, I fired up my editor to explore the problem. It proved to atrociously difficult as I didn't have any background in anything similar but with the help from my brother, I was able to make a scrappy algorithm that worked.<p>I reported back my progress and asked for additional $25 for it but the client refused, saying that he hadn't given his final say. I was dejected but felt foolish more than anything else. Looking back, I can't help think how anyone would pain in giving something as meagre as $25 (at least, for someone in United States) for a someone's hard work.<p>If there is one thing I can glean from my story and author's is that businesses, at least most of them, are ruthless. It doesn't matter who runs them, it's just an unspoken rule that you don't give what you don't owe. You don't shower sympathy or, do things that aren't in business' best interest (long term / short term). The only thing you can—and should—do is be ruthless yourself. Negotiate for more confidently. Move on if you're undervalued. Never think of owing anything to any entity.
