Got an internship some time after that. I didn't have the greatest GPA, and had to drop a few classes. I'm not the greatest student for a formal education, but I'm genuinely interested in a lot of stuff and pretty good at self-educating things that matter to me. Performed good enough on the job to get a full-time position without an interview.
From there I went into business with a close friend doing agency work. We eventually went through a tough time business wise and got acqui-hired by a larger agency.
Second low point was around then when our business hinged on getting one big client. We pitched the business and didn't end up getting it. Luckily we were already in talks with the agency that acqui-hired us, so we used that as a fallback. It was a good fallback for us, the pay is good, but it isn't a startup :-)
