My opinion is that CAD is a communication tool.

CAD helps you lay out your ideas and communicate them to other team members. CAD helps you better communicate your ideas to the more logical part of your brain and flush these ideas out in more detail. CAD will help you communicate to your manufacturing team exactly what parts you need made and communicate your assembly team where those parts go.

CAD, however, will not take bad ideas and turn them into good ones. CAD won't make up for deficiencies in the other areas of the team you're trying to communicate with. CAD won't make a plan for you, just give you a method to better communicate your plan to other.

Also, learning to CAD will not teach you to design. Just because something looks like it will work in CAD does not mean it will turn out the same in real life.
