For 15 years I was an employee in a state company with very good income, especially when I was working in big oil company with extra good pay. But when the opportunity came, I changed occupation, completed the necessary education and went into private business and entrepreneurship. After few years, I did not have a wish to go back to the previous job, which maybe had a safety net, but without a chance to develop personal ambitions. Because of all of these things, I enrolled in the doctoral study focused on entrepreneurship and innovations because it goes well with my personal ambitions.
I think that the lessons I have been through so far were very useful to me and helped me to prepare for research challenges.
