The document summarizes what the author learned in their first year as a full-time programmer. Some of the key lessons included that programmers are not necessarily the most important people on a tech team, and that qualities like collaboration, quality work, and avoiding "rockstar" behaviors are more important for success than being a highly skilled coder. The author advocates learning where one's strengths lie to best contribute, such as through documentation, code reviews, or testing. Asking for help from others and tracking one's own growth through blogging or public speaking are also recommended. Diversity, inclusion, and avoiding tokenism are important both for the team and for building products for diverse users.
