We believe reality gets to be somehow misleading. We come to this world as a being of infinite possibilities. Growing up we sometimes tend to forget it, we rationalize our perceptions and feel like we are constrained by what surrounds us. The secret to happiness...
....seems to lie in realizing that we create everything that surrounds us - Material possessions, Human relations, Carreer possibilities, etc...
As a technique to ensure our happiness we usually keep that in mind while going through our day to day existence. What we then realize is that we cannot blame circumstances or people for what happens to us as we have created their existence within our life.
It's all in our heads, let's make the best out of it while having fun!
