Knowing how you developed self-doubt can sometimes help lead to recovering from that condition. You can build self-esteem by getting to the bottom of how it happened. Some people did have self-esteem at one point, then lost it. Some never had it in the first place.
No matter how you determine what causes your self-doubt, you will be able to overcome it. It does not matter if it is something that developed over time or something you learned in childhood. You can work toward building your belief in yourself so that you can overcome self-doubt.
Limiting Beliefs Learned in Childhood
Many people learn to put off their dreams. And limit their ideas due to well-meaning parents (or sometimes they are not so well-meaning but perhaps abusive parents) who are also stuck in their own self-doubting lives and cannot ever envision anything different. It happens a lot in communities where people are often born very poor and end up lacking experiences and education to see beyond their own lives to the possibilities that are outside their world.
It is not usually the fact that parents want to keep their kids from dreaming; they are just trying to be realistic. When their child tells them about their big dream to travel the world and become a writer, they react in fear and make statements that may be statistically true, but that limits their child.
An example, they might discourage their child from becoming a writer by telling them no one makes money writing, or they might prevent their child from becoming anything that is above what they are used to due to the fear of the costs and the fear that their child really can not do it even if they try. But this is only due to their lack of success and understanding of life.
It rubs off on the kids. That is why statistically, most people do not break out of the class they were born to. The exciting thing to remember is that some people do, and the reason they do is they were able to see and envision the possibilities and then take action to see it through.
Until next time, stay safe, and keep the faith.
