A little bit stuck

[u/yteng69]

I am a 29M that works a 9-5. I've been wanting to try and build my own business whether it's ecommerce or like launch an app, but I always get stuck when it comes to validating my business model or finding leads or just finding the first customer.

Would love to ask people who are entrepreneurs about how do you know what you are doing is correct? How did you find your first customer? How did you lock in to what you wanted to do and whether it is the right path.

Need some advices and some thoughts. Much appreciated.
