I am rephrasing my question as my other one was not specific enough and was put on hold. I am worrying because I dropped out from my first uni degree, entirely due to personal health and family reasons, even though I had almost completed it with full distinctions and scholarships for further academic development. Among other things, I had won research funds for some innovative projects where I would have contributed to my field and worked together with some eminent professors. I lost all that...
Four years later, my personal situation is getting better and I have established a relatively successful career in my field from within business. I worked hard as an employee and in the past two years had the opportunity to help invent, together with my boss, a revolutionary tech business model that is now also written about in academic journals. I am very satisfied with my job and income, and we are recognized within our industry niche.
However, I often wonder if I could make that further leap if I did top up my academic credentials. The reason I feel this way is because I sometimes feel puzzled whenever my peers start discussing high theories and models that I haven't. It makes me feel that despite my achievements so far, I might be missing some important knowledge, and training, that could be important for the future.
For example (just an example to clarify the question): Let's imagine I designed a few incredibly useful and profitable mobile phone apps, even though I have no programming skills and know little about computer theory. My boss and the software developers then improved it and made it scalable. I got some recognition and promotion in my company. ...but will that be enough if I wanted go and hold an industry seminar or lecture on mobile app business? Would that alone help me get a higher position in another company? Let alone become a "thought leader"? Or would I need a computer/programming/engineering degree if I wanted to climb the ranks?
P.S.: Just to be clear, I am very satisfied with my job, so I apologize if I sound over-zealous and maybe "dreamy". I just think I may not find fulfilment.
I hope this time my question is more clear and within the standards of stack exchange.
