Good ideas (and the ability to recognize them) are very valuable in my opinion. It also depends on what you mean by an idea:

- A todo app better than the existing ones

- A todo app with these 3 features

- A todo app with these 3 features, here's how the UI would look

I have tens of ideas, but maybe 1 - 3 that I believe have a meaningful chance to become successful and generate income ($20k annually or more) with great execution. I find it hard to come up with ideas that have a fairly clear path to success and can generate income.

I have hundreds of ideas which I think can generate revenue of the sort you describe, but they need significant work each (execution). Note that $20k annually is already full annual salary in half of the world too.

Can you share some out of curiosity? Yes, I know that $20k is a full salary in many countries.

A very simple one: interview scheduling tool integrated with multiple calendars.

Eg. when interviewing, sometimes I have a pool of interviewers, and I want a pair to be offered to a candidate (they only see time slots, obviously) with certain internal conditions (one expert from this pool, another from this pool; eg. tech stack or timezone), while equally loading all of them.

Sounds simple but I could never find a tool that does it, and I believe companies might be interested just like they get tools like calendly just for limited purposes.

iCal format is simple on the face of it, but companies have restrictions on the feeds, and accounting for recurring events and working hours is not as trivial.
