Honestly? Nothing.

I think I would get more from investing in something boring-yet-reliable and finding another job. Do you really think that an idea someone gave you on the internet is likely to provide more happiness than having a cushion and retiring earlier?

At the very least, you should hold off for a few years until you have an idea and the technological/business skills/partners to implement it.

Given what I value now, having a cushion and retiring early would not provide me much happiness so it is not hard for sth else to provide more happiness than that.
