Simply look around

If you want to view paradise
Simply look around and view it
Anything you want to, do it
Want to change the world?
There's nothing to it - Willy Wonka

This, I think, may be easier said than done - step one: look around, step two: see paradise. Perhaps when you are the worlds greatest chocolatier that is how life really is. 

What I also think is that there is a real nice note of truth in the concept of choosing how you see your world. Here is a theory that I manage to subscribe to in my good moments: 

Your reality is a combination of the circumstances in your life, and how you choose to view those circumstances.  ​
​

Clearly there are challenges with the idea of choice in the concept above. It places a lot of responsibility on the individual for their health and happiness. There are accidents, poverty, disaster and inequality in life; some are born to privilege and others not - it’s unfair to ask people to simply choose joy in the face of adversity. 

There are clearly parts of the external world which are beyond our control. There is also an internal world that each of us has some influence over. It seems to me that on occasion it is possible to view a mistake as part of learning, to see that a challenge is also an opportunity and to take the stance that in many ways the life around us is something to be grateful for. 

Life isn’t a paradise, it is a series of complex elements and happenings swirling around beyond and within us. One of those elements though, may well be your perspective.
