In affiliate marketing, regrets often come from wasted time, wrong choices, or lack of action. Many beginners jump into a niche without checking if there is real demand or spend months on content that never gets traffic. Others regret not building an email list earlier, since it is one of the strongest ways to keep in touch with potential buyers. Some people focus too much on promoting expensive products and ignore smaller ones that could have created steady sales. There are also regrets about giving up too soon when results were just starting to build. What lessons do you think are most important for avoiding regrets?
