do you mean customer validation has to be done with an idea or concept. I thought having a MVP helps in that customer can more easily understand what you are talking about.
Talking to your parents and showing that what you are doing is likely to be beneficial. Probably you can shows the codes posted at github and then show where the coder is working--running their own show or running the show at some big company etc. If they see that what you are doing is what guys much older to you are doing and is likely to help you, probably your problem may get solved.
"Google was never really interested in the idea of "open" — yes they love "open" when it helps them, but it's actually a very opaque company which has a "my way or the highway" mindset."... Shades of Microsoft
If you want inspiration you need look no further than Winston Churchill. You could try to overcome it. I really like the card idea below. Why not Freelance... since most of it is done over mail.
I might be asking myself these questions...
How important would that feature be? Would having the feature make a lot of difference? With this feature would your product be better? Will that feature alone allow you to sell better? How long would it take your competitor to add the feature? Would having this feature help your competitor to sell better?
If competitor will take time and will help him sell better then one option if you develop the feature is you could sell it to him if you can't compete
"is probably being done better than I can do it" .. probably you answered your own question with this. How are you going to take him on based on one feature if he is better? IMHO, Get going on another idea.
"right way of presenting myself"... I constantly faced this problem. There are lots of people I know who can write resume to suit the job for which they are applying. May be resume writing skillset could help in this.
In one of his talks Guy Kawasaki said (during his speech at Haas Business School) "It might be better to be lucky than smart". That said doing as good a job as you can helps!
I would suggest stash most of it safely.. under 250k in different banks. Take a holiday, tour the world. Who knows you may get some idea. Come back and start afresh. Real estate appears to be in a froth so I might just wait.
