<human>: Can you give me the gist of the text in a nutshell?

I am a career junkie; my entire life since the age of twenty has been focused towards the achievement of professional goals (antimicrobial drug discovery). I have found that with each major accomplishment the the thrill and satisfaction is diminished which compels me to seek big and greater gains! My first big high was journal publication in graduate school, then publications that were cover features, then work highlighted in world renowned arenas, after that it was grants on topics far and wide -until I thought of myself as a wizard in the field. My last big achievement was the contribution to a book detailing the future of drug discovery. However none of that compares to what I'll be doing Thursday.  I will be proposing a biotech spin-off to a group of investors. Starting a biotech from the ground up has been a lifelong dream. 

Reddit would you share some of your experiences regarding career achievement thrills and milestones? Any advice you'd care to share? Any critical lessons I should be mulling over?
<bot>: Thursday is a huge milestone in my career and I'd like to know about similar experiences and maybe how it made you feel or lessons you learned?
