The genre is loaded with people who are better at marketing than giving helpful advice. Even so, some of these books are valuable at least to get you to the point of being more introspective and develop a clearer understanding of what you do, don't do, say, and don't say affects the way people perceive you.

Some of these books focus on tasks. "If you do this every morning, you will be better at X or Y." Maybe. Maybe not. Whether I make my bed in the morning doesn't particularly influence my behaviors and attitudes throughout the day.

Since I'm in the professional development field, I tend to develop programs that build competencies. The ability to handle change, dealing with ambiguity, holding yourself accountable, etcetera. Generally people cling to tasks because they are tangible. Building competencies takes more work and dedication.

Ultimately, the way we improve is through a combination of building habits, developing empathy, and questioning our initial perceptions. It only happens if you are committed to positive change. It doesn't make a difference if a best-seller tells you how to do it or if you figure it out on your own. Without a willingness to identify what needs to be better and a willingness to work, it won't happen.

Good luck and best wishes on your journey to a better you.
