" There are four obstacles.
First: we are told from childhood onward that everything we want to do is impossible.
The second obstacle: love. We know what we want to do, but are afraid of hurting those around us by abandoning everything in order to pursue our dream.
The third obstacle: fear of the defeats we will meet on the path.
The fourth obstacle: the fear of realizing the dream for which we fought all our lives. "
― Paulo Coelho , The Alchemist
