Some times, be a child who believes he can fly. The wright brothers never stopped believing and they became the right brothers to promote flight.
If you have an product idea which others find silly. It doesn't mean people will not buy it and you can't profit from it.
I have products that took many long days to create but profit turned out lesser than another which I took an hour to create.
It took me faster to sell a few hundred thousands than to sell a 5 dollar product.
It took less than 15 minutes to clinch a few thousand dollars deal within the first meeting but took many weeks for a lower payout service which did not work out in the end.
My friend, keep on striving for the next breakthrough.
The best is yet to come and you might be very close to success already for the next breakthrough.
Let me know if you need help or an extra boost.
