Hi everyone, I'm finally finishing my Master's in theoretical physics. These past two years reminded me of how easily I become excited and lose interest. My thesis is on computer simulations which also helped further develop my programming skills (I do love programming). As super exciting as everything was I did not forget to keep true to myself and loose interest at some point, which I managed to overcome by working on an independent project for a short time. Anyway, the time has come for me to decide what to do next and unfortunately I have to react to PhD openings quite soon. As the titles says, I'm afraid to commit to a PhD because of my short "attention" span. I'm afraid I may loose interest in the first year and the thought of having to write up 200 pages for the thesis, scares me. I was thinking a job in the software industry with the ability to change jobs often, may keep me more interested, but again, my experience tells me that most of the times, expectations don't meet reality. Could you share your experience in similar situations or do you have a piece of advice I could use in making my decision easier (or worse)?
