This quote by Phil Kolter means that while it’s possible to learn the basics of marketing relatively quickly, it takes a long time and a lot of practice to become truly skilled and proficient in the field. Marketing is complex and constantly evolving, and requires ongoing effort and continuous learning to stay up-to-date with new trends, technologies, and strategies. Becoming a master of marketing is a lifelong pursuit that requires dedication, hard work, and a willingness to adapt and learn.
