Caution means having the control to either think things through or proceed in a manner that is slow and meticulous, and the word cautious is also accompanied by fear and doubt. On the other hand, being careful is not about harboring fear and uncertainty. Careful means to follow through in a well thought out and strategized way, and careful leaders exude confidence, while cautious leaders do not.
One of the main differences between careful and cautious is that cautious is a kind of emotion, which is complemented with a whisper of fear. On the other hand, careful is not a fear-based emotion. Careful is more like action, as in “She was careful not to make noise.” In the business world, careful includes things that can be done, such as gathering information and interviewing experts. It allows you to engage more in your work. An example of being cautious is a parent who reluctantly gives their kid the keys to the car before he or she feels they are ready to drive.
