When it comes to pursuing goals, limiting beliefs can be very destructive for the person trying to change their life for the better. Their very nature is to highlight what you think you cannot do or accomplish. For example, a popular limiting belief is thinking that you cannot learn a new technical skill if you did not acquire it in a school or learning institution.
This is a very disempowering perspective to have on your own life. Especially today. When so many people are getting into business/entrepreneurship and handling so many aspects of the businesses themselves. Podcasters that edit their own podcasts. Content creators that market their own brand and self-publish.
Using multiple skills to solve a single problem. Creating a life, they have always wanted.
