Power the generator with vegetable oil. There are multi fuel generators that are designed to work well with that kind of fuel. You could also use them for heating which is very useful in Northern regions where you usually need heating and electricity during winter.
I started doing Capoeira and learning Portuguese with 40 years. I am fluent in Portuguese now after three years. My Capoeira skills are still pretty basic, but I progress and for the first time in my life I feel like I really have a grasp on any kind of sports.
I also changed from marketing to IT last year and I am getting really good at what I do.
It helps if you have a reference system for your new knowledge. I studied computer science which helps in my new job and I had French in school which helps with Portuguese.
So don’t worry. Keep learning, avoid stress and drugs and prioritize getting enough sleep. You’ll be fine!
