Following your dreams automatically leads to contentment and happiness. If you aspired to become a great artist but ended up as a doctor, you may make a huge amount of money and earn reputation but your mind pinches you whenever you see some great artworks in an exhibition. Following your dreams will make the universe open doors for you where there were only walls. Success might not be an immediate reward for chasing our dreams but ultimately it has to succumb to your desire.

Thanks @javybar for your true inspiration. You are great person.
