Take your hobbies seriously.
I have no time for a hobby these days. I don’t even know what my hobbies are. Perhaps it doesn’t matter how I call them; no matter what I do, I take seriously.
Once we start doing something seriously, it can turn into an opportunity. There are many people who turned their hobbies into their businesses, as you might have seen some of them around you.
Hobbies are NOT for killing time. They can develop your skills, explore your creativity, and create a new business opportunity—if you take them seriously.
