I like the small company that I was around and that they cared about my progress as a professional and future business employee.
What I wish was different
I wish I focused a little bit more on going through how to set up a new customer and what it takes to get a new customer. Also what it takes to start and mantain a business like that. What it looks like to lead a team of people.
Advice
Just put yourself out there. Try to learn as much as possible from people who have done the same with their mentors.
