A habit that has really improved my life is a commitment to life long learning through engagement in a hobby. For me, learning is a far better antidepressant than the ones that Big Pharma have come up with. My hobby is my home computer lab where I tinker, break things, and learn. While sometimes frustrating, this is all part of the learning experience and ultimately leads to a sense of accomplishment when a problem gets solved. I make it a part of my day to build, grow, and maintain my home lab.
Learning is also a love as it truly has to be. I pity the people who only learn when it is a requirement; they lack hobbies or interests. The neat thing about learning opportunities is that they can be found in many places. I discovered the home lab hobby at one of my local libraries that has a technology center. I visited the technology center and saw what people were doing. The next thing I knew I was diving in head first into the next learning opportunity.
I recommend more people try out a hobby that will help them grow and learn. Hobbies and interests that engage you will improve your life as they have my own.
