Advantage over your competition is something every entrepreneur seeks to achieve. As an online seller, that can mean — among other things — putting the customer first; making sure your items are as described; pricing appropriately; and following best practices. Another way to score an advantage over your competition is by reacting to change in an appropriate way. Some entrepreneurs react to change by first panicking, then worrying, then complaining to anyone who will listen. While these people are spending their time panicking, worrying and complaining, other sellers are continuing to sell while incorporating the necessary changes. It’s OK to question and be educated when changes come, but successful business owners keep on keepin’ on.
