<p>I really enjoyed reading your analytical breakdown of your perception of mistakes in your business endeavor. This is valuable advice for the interested entrepreneur.</p><p>I'm interested in starting my own collectible trading business. There are many people trying to create deals with me, and many middle men appearing. My intuition in this is strong, in detecting ulterior motives. Your response here has helped me put this in perspective a bit. </p><p>In a competitive world, I believe skepticism and intuition of the motives of others, is not only necessary, but also, a much needed skill for success. </p><p>That is not to suggest I couldn't be overly paranoid, as you stated in regards to perception, sometimes it can produce inaccurate results, but I've learned to trust my instincts over time.   </p><p>I've also just encountered my first mistake as a seller. Missing merchandise. I'm not sure how to handle this productively, but my idea is to offer a similar merchandise for free, as well as offer a refund for the missing merchandise if this is not substantial. Hopefully the costumer is cool in this respect. I still have to figure out how I made such a critical mistake though! There is so much to consider when it comes to managing a business. </p><p>Thank you for taking the time to compose this excellent information!</p>
