What that discouragement as advice and follow it. For example if someone say:
"Dude, don't make that game by yourself, it will never get done!"
That is a good comment IMO, that means that you will never complete it, which is true 99% of the time. Maybe if you can't program, get into concept artism, moddeling, music composing, etc.... and you can still take part in game makeing.
If you can explain a little more what the people said that was discourageing you maybe we could help instead of just agreeing and whining about our own !@#$%.
