Do you have a lot of free time?

I don't think that any normal person who has a job and a family has a lot of free time. It's something out of the realm of fantasy, really. So you need to understand that you always have to sacrifice something. Or your profit. or the present, where you can spend time with loved ones. BUT if you want to have a really cool rest later, then you need to work and try now. Perhaps you will appreciate the opportunity to join the electric charging infrastructure  and develop in this area.
