When I am not making money, during my free time, I write my own

books, and I'm currently developing my own video game, alone, and coding.
What are you doing to improve yourself?
What are you creating, or learning?
Are you doing something that will benefit you in the future?
I believe that it is good to have more than just one skill.
Some day, a robot might take over your job!
In this day and age, we all should be learning more than just one skill.
We should all have a backup plan.
