You should always be learning something new. You don't have to be amazing at it but you should try and learn something new to keep your brain active. You should also learn physical activities as well. Learn a new stretch or add a new exercise to your work out. If you don't exercise please start.
In addition to the fun facts about the tech industry you will see my progress on my electric skateboard as well.
I have never skateboarded in my life but I went to the parking lot and tried it. Why not? Just try something new, when you try something new you learn.
