I've always had an obsession with learning new things. As long as I can remember, I've looked at the unknown with curiosity, as opposed to fear.
Maybe it is a generational trait. Maybe it is how I was raised. Whatever the reason, I think my willingness to figure things out is one of the reasons I have been successful in life. If I don't know how to do something, my goals are not dead in the water with my ignorance. I just have to figure it out.
It may take time and will certainly take effort, but we are surrounded by ways to learn new things. You just have to be willing to do the work. You can search the internet. You can read a book. You can ask for help. You can watch a tutorial. You can take a class.
Whatever “it” is, be willing to do what it takes to figure it out. Be brave. Do the research. Take the time to learn the answers. Don’t let fear of the unknown hold you back. Figure it out.
