The thing is, if everyone thought like that, then nothing would ever get invented
I know where you are coming from and it's one reason why I've never really put much thought into coming up with physical innovations. But there are infinite possibilities for inventions and watching Dragon's Den something I think "Crikey, that's really smart". One guy I remember made this device to water your plants when you were on holiday, it was cheap, came in different sizes, reliable etc and was all round a brilliant concept I thought. He blew it on the show in the end due to trying to deceive them about what he was offering (not including North American market, something like that) but I was in awe of what he'd achieved.
yeah i remember that idea, was very smart but iirc he walked away with no deal due to lying or something like that
Another way to do it is post it to yourself via royal mail special delivery.
what would that prove?
