ask anyone who has been at several tradeshows a year for several years.. it's hard to believe .. i wouldnt have thought it either
I believe you.
My older brother used to do Card Shows (back when they were very popular - late 80s into the early 90s) - my dad would drag him (and me) around to dozens of card shows a year and he did this for a few years. My brother was so into baseball/football/basketball/comic cards (and comic books) that he spent a better 3-4 years of his early teens doing this.
After doing it for so long and always traveling, he grew tired of the work it required, keeping track of everything, sorting through other people's goods to expand his collection, tracking down rare and expensive cards....he burnt himself out. After he hit that point, he lost his interest in his collection - sold 99% of it off, only keeping the high end items.
He does almost the same thing with his work now - he runs his own business and he keeps working and working and working and never takes a break. He's almost burnt himself out on it and gave up a few times. I had to sit his ass down, tell him to take a vacation (he has the money to go wherever he wants) and let his employees run things for a week or two. After his break he comes back with renewed vigor and he's eager to get back to his work and he enjoys himself at work again.
You have to take a break now and again, don't burn yourself out on something you enjoy. Once you burn out on something you once found enjoyable, you generally loose your interest and taking a break doesn't do it for you anymore.....then you're left with two options:
1) Suck it up and be miserable
2) Move on to something else you enjoy.
My suggestion, take a break. After a bit of time (couple of weeks, maybe a month), if you still feel the way you do now about TPU, then you want to look into option number 2. If that's what this comes to, the I wish you nothing but the best in your future endeavors.
