We can live a life being aware of unlimited possibilities or insecurity. The brain is our master. It can make us do wonders or make us feel miserable.
Our insecurity has more downsides than positives. Imagine the misses in life because of it. Some people realize late in their life about it. They die regretting.
None of us are perfect. We have to accept it. But this does not mean living an invisible life cursing our life. We have to add more stars for those misses.
Marie Curie, Stephen Hawking, and numerous examples are in front of our eyes. They did not let disabilities come in their way of glory and making the world better with their innovation.
