Recently I started writing ideas every day and I keep it as my daily habit (10 ideas per day) which I really like (inspired by James Altucher - I like his Idea machine thing but otherwise his newsletter is pretty bad and too annoying). So far I didn't execute anything just writing it down to my paper notebook.
It's been already 2 months so I have written down already over 600 ideas. It's not just business ideas it can be anything that comes to my mind about my life and so but mostly I try to come up with project ideas. As I mentioned before I didn't make anything yet but a few of the ideas are promising (I guess haha).
I've been regularly checking the product hunt website. You can get some inspiration and see what is going on around.
I cannot recommend to wandering there too often cuz some of the ideas can be super close to your idea and you lost your motivation when you would find out. It happened to me recently and I rejected the idea and didn't start making it. I know you shouldn't really care about it cuz you usually never be the first but still, it hurts hehe.
Anyway, I don't give up and will continue to look for the right one.
Stay with me. Efran.
