Started a company to help brother, his family and my mom out and
to keep a mortgage going. It's doable. I'm INFP. If something
seems hard, find an easier way. There's always an easier way in
business. Give the big guys what they want (taxes, license,
whatever) but don't drive yourself nuts over it either; it's
just paperwork.
Be honest as you can be in advertising, but know you have to use
a little hyperbole (exaggeration). I try not to use too much
though. The temptation is strong but I just can't.
13 years now. Always a struggle. You work 16 hour days
sometimes, other days, you do nothing but fart around. Is it
worth it? Well, you have to be emotionally stable and not let
every situation with customers throw you, or every threat get
you scared. Always be willing to walk away from a job without
hesitation. You can't save the planet and some people are
gamplaying. Most people are decent and reasonable though.
It's not the glorious thing people say it is, but it's not a bad
way to do things.
I only know the US rules, but I suspect similar things apply
elsewhere.
