I know this is good advice, but it is the thing that holds me back the most. I live a simple life and I literally don't have anything I would pay for that I could also conceivably build myself (any ideas I have tend more towards hardware than software).
The few ideas I have are for very niche needs (think homesteaders / permies) and I already make enough money writing software for others that the risk of investing in hardware for a tiny, tech-averse market makes it a foolish risk / payoff proposition.
Everything else I could want hardware-wise already has a startup that I would rather support than compete with.
