Friends are great for high-fives, but useless when it comes to constructive feedback. Your best bet is to attend maker/hacker/startup events and tell people about your project. If they seem interested, go into detail about your plan: why you started it, what problem you're trying to solve, and how you're going to solve it. Be open to new ideas. (Sometimes you discover that your 'goal' isn't really your goal, but a shadow of your 'true' goal.) Adjust your plan accordingly.

I'm only a few years older than you and on a similar path, so you can start with me if you like. (Also: put your contact details in your HN profile so people can reach you!)
