EpicFailure

I did several career tests and based on the results of what might be an ideal role for me, what role/industry/function do you think best unites the following? - work involving lots of public relations and presence at events, trade shows, conferences; - highly autonomous work rather than teamwork. The most obvious answer to me is being self-employed (I don't want to be, see my other post with negative entrepreneurial experiences...) or an academic/research professor who does most of the research by himself or at most with a really small team, but after that moves a lot to present the work, travels around the world to discuss the ideas and always maintains a huge network of contacts. At the moment, I am quite interested in that option, though I know it means taking a hard path (postgraduate, PhD, etc.). Do you know of any other jobs/careers/roles/functions that fit the criteria I mentioned above? Thank you

Hello everyone, I have a pretty serious problem. Until 4 years ago, I was a straight-A student in the middle of an undergraduate degree in International Affairs/Economics at a quite prestigious European university. I had a minor sports injury which severely affected my performance (due to chronic pain) and reduced my integrity to prepare for exams. To distract myself and breathe new air, I started a gap year and soon created a few businesses, which have brought me into various countries of the world, however neither of those initiatives was really related to my studies (internet marketing and tourism/entertainment) and, despite the great experience and exposure, they were ultimately a failure - in part due to my own loss of motivation. The year after, I started working on a fixed contract basis for a big and famous company, though still somewhat unrelated to my degree (financial services), and after finishing there I realized that what really motivated me was to work in the field of the degree I had chosen to study: international relations, intl organizations, diplomacy/related, etc. I would never go back in time, because during these years I have met wonderful people, learned a new language, and done things which I probably would have never done otherwise. But the price was high: I will be graduating almost three years later than the normal duration of my degree and with grades which, while not being bad, probably do not meet the requirements to enter a good grad school or even an internship in the field I desire to work in (I was basically doing the exams during these two "gap years", self-studying and not going to lectures). And all experiences I gained in these years "off track" are not formalized. There is no "certificate" for them (at least, not pleasant-looking ones...), no credentials. I would appreciate any advice on how I could ultimately return to the career I had in mind. For example, do you think I could/should write about all this in motivation letters despite not meeting the requirements of the places I apply to? Won't everyone think that if I failed once, I will fail again?
