Humans originally have only two fears. They are fear of loud sounds and fear of falling. All other fears are acquired, not inborn.
We grow up with fear and learn to avoid new things. We always think about maintaining the status quo. The fear of failure is the reason why adults are afraid to try new things.
If you do not take a risk, you will never fail. But unfortunately, you can’t succeed without risk. In order to make the most of your potential, there are times when you must take a risk. To live your ideal life, you have to deal with fear and take action to overcome it.
