We are in this kind situation at Dabble Lab aaaaaallll the time.
I understand people that tend to do this. Their idea is something that they have spent time thinking about, and hopefully trying to figure out if this is something that makes sense to pursue.
However, no one is going to take your idea about a travel site, because beyond coming up with this idea, you still have to execute. And without execution your idea is worthless.
I have recently met a gentleman who’s Instagram account is growing at 5k followers a month and is now up to 90k followers. It took him almost 2 years to get to this point. What do you think are the chances that if he told someone his idea two years ago they would execute? Probably very slim.
