We live in our own little bubble. There are social, personal, emotional, religious and many more spheres we are living in. We fear to leave these spheres, it is the unknown. It could bring our bubble to burst.
We have to step out of our spheres of comfort. We have to leave our social concepts. We have to discover the unknown. We have to expand our spheres until the bubble bursts open and we reach everywhere. There are no limits, there are only spheres of our mind. Open the mind and leave the spheres behind.
