Too many people these days like to knowingly, or subconsciously, put all their eggs into one basket. This is just a way in which you cannot live. I too have lived in the life of just purely focusing on one thing that makes me happy. That one thing that you know makes you happy more than anything can be gone in an instant.
I hate to be frank here, but people - and things - can be gone in an instant.
Speaking from personal experience all my eggs, or happiness, was put into soccer. I still play my favorite sport at the best University to this day, but last year was a bit of a rocky patch. When I injured my leg before the Fall season began I was heartbroken. On October 2nd, 2017 I had hamstring repair surgery. Not being able to play broke my heart. I was upset and thought life was over as I knew it.
Thankfully I had some of the best friends in the world to help pull me out of my funk. They showed me that life is about more than just soccer. My friends turned a bad situation into a great one. I got closer with the softball team here at Troy and now they are my best friends. My track friends forced me to hang out with them rather than be sad in my room, and now they come to all my games. Even my professors showed me that school can actually be fun.
The next spring semester I found happiness in soccer, friends, family, and school. With this balance in my life, I knew that I would never be in the state of sadness I was in the fall. With all my eggs spread out into multiple baskets, I know that I will always be happy. For every 60 seconds, you are sad that is a whole minute of happiness you can never get back. Make sure you are living life to the fullest by not putting all your eggs in one basket.
