Do you know what it takes to make money from your ideas? Most do not but the good news that it does not require a lot of effort just some thought and a few key concepts to prepare before hand. Business plans are fine but before spending hours on planning, development, and even more on funding an idea, make it work first. Check its viablility then do the ‘prep’ work. You want to spend nothing or next to nothing to get a feel for the potential of your idea not a bankroll for a flop.
Our daughters have grown up watching me build, tinker, and repair everything from a chair to the ceptic pump. Generally, if it can be built, I can take it apart which of course allows me to fix it. Similarly, if I can imagine it I can build it. Yes, far too many years troubleshooting and building computers is in there too.
