What hobbies do you have that you have found to benefit your preparations ?
For instance, I have two that I'm finding invaluable.
The first is my small, hobby metal working shop. Having the ability to design and make items that are expensive or unavailable to order/buy.
While it's a fairly expensive hobby to get into, it can and does have the ability to create an income stream doing work for others or making and selling items.
I've also made sure my equipment is able to be powered from a small generator if it becomes necessary.
The other is Open Source Electronics. Platforms such as Arduino, TI MSP Launchpad, and Raspberry Pi along with the multitude of electronic sensors, motion control devices, and many others components allow for the possibility of custom controls, monitoring, or other needs.
Not growing up with computers, I'm still trying to learn code writing, but this has many possible advantages much like my metalworking hobby.
Hunting, fishing, and gardening are 3 other hobbies that come to mind for obvious reasons, but I found myself wondering what other hobbies people had that benefitted their prepper/homesteading life-style ?
