<blockquote>This is, far and away, the most important lesson to learn as a consultant. People who are unsavvy about business, like me in 2009 or like most freelancers today, treat themselves like commodity providers of a well-understood service that is available in quantity and differentiated purely based on price. This is stunningly not the case for programming, due to how competitive the market for talent is right now, and it is even more acutely untrue for folks who can program but instead choose to offer the much-more-lucrative service "I solve business problems -- occasionally a computer is involved."</blockquote>
