Something Warren Buffet said.

Be prepared to look foolish
Investing is an intellectual pursuit for many, so the ability to ‘look right’ can be strong. However, successful investing requires being able to bet against the crowd and look foolish sometimes.
Though markets are generally rational, they occasionally do crazy things. Seizing the opportunities then offered does not require great intelligence, a degree in economics or a familiarity with Wall Street jargon such as alpha and beta. What investors then need instead is an ability to both disregard mob fears or enthusiasms and to focus on a few simple fundamentals. A willingness to look unimaginative for a sustained period – or even to look foolish – is also essential.

I guess you can look at this from both directions? (an ability to both disregard mob fears or enthusiasms)
I do try to disregard the mob fear aspect, there seems to be plenty of it right now!
I do also try not to be over enthusiastic, yes things have been slower than I at first anticipated, but I keep asking myself, does the company have a good product? will it be accepted for use going forward? does the company have more than one platform (horse in the race)?
do they have enough money at this point before better sales come through?
are they looking at more than just one market?

I have come to the conclusion that if the answer to these questions is YES, then I believe I am still on a winner, I may look foolish now to some, I certainly hope I am not looking like that down the track?
But risk equals reward, I really do look forward to getting dividends on this one day.
