Remember the competition between Edison and Westinghouse. They did not create thousands of failures, but found thousands of ways to not make a long life light bulb.
We make choices and find ways that work and ways that produce minimal benefit. Learn from least productive ways so that you can improve to be better. Continue to take risks and try things that you find interesting till you find you find your passion.
Remember some things start out as an unknown, with no skill and they can turn into a passion.
EXAMPLE: I have worked my whole life in Enterprise Storage. From Digital computer corporation to Compaq, Microsoft, Brocade, EMC and now Dell Technologies. Among the way I worked in many startups attempting to strike it big so that I could retire into some of my passions that do not pay.
Along the way, I went from being a developer to a manager into training and now in Technical Marketing. During a rough patch in my career 17 years ago, the startup I was at failed and I was left unemployed and wondering how to pay bills and support my family. I did as many do using the credit cards to support us as I did job interview after job interview.
I went to an interview and during this interview I realized I could do the job, but it was not a passion and would I really want to do the job. I took the job as they liked me and I needed to support my family. I dove into the virtual world of VMware. It was not because I wanted to do it since it really did not have much to do with Storage other than use it on the back end to run the images, but it was a paying job. The more I dove into learning it, the more I also realized others were afraid of the tech and I became a point person that people turned to for help. I had increased my value without knowing it at first.
I later on changed jobs to Isilon, a file based storage startup as they were teaching customers how to use their radical new storage appliance with real hardware and I knew in my heart I could create a better way to offer training without having to tie up major capital in having real hardware in the classroom. I ended up working with a Development team and created our Isilon simulator. Since then, 10 years later I have a job I love, I create year round new training based on new releases of our OneFS File storage system and help our employees, partners and customers learn how to use our hardware and open source projects to enhance their business and cloud use.
If you asked my 17 years ago if I would have a job I love and have not continued jumping from place to place every 2 years or so, I would have probably said no. Today, I love my job and what I do to help so many around the world.
Moral of my story for you is NEVER GIVE UP, NEVER STOP TRYING, YOU CAN AND WILL find your passion that you can enjoy for life.
I believe in everyone here that they can and will find that passion to drive themselves to new heights!
Sorry for the long write, but I hope you can gain strength from my sharing of my career to continue to push forward and look at things you might have never considered. You never know when you will find something that becomes a life long passion.
