See Any Situation As an Opportunity

Let the next sentence really sink in.
It is not what happens to us, but the meaning we give to it that determines our fulfillment.

It’s always how we receive the world and interpret it that determines our wellbeing.
Not the actual events. 
Follow this to it’s logical conclusion and notice that you can make any event a great one.
When confronted with any “negative” event think, “How is this my best moment?”.
This forces your mind to see the possibilities where you thought there were none. 
You learn to love any situation.
You enjoy the “positive” situations more deeply and enjoy the challenge of “negative” situations.

If nothing can deter your spirit, you become invincible in a way.
When nothing can stop you, the world opens to you.
