Thank you for the advice.
The issue that I'm facing as an engineer is , everything I want to use has already been built, maybe I can come upon with improved versions of them.
What products annoy you? That could be an indication a product isn’t really fulfilling your needs.
Are there any software products/services you want that are too complicated and expensive? Maybe build something easier, cheaper, and more niche.
If you’re still at a total loss, you might consider partnering with an expert in some area that has a problem you can solve.
