When young, I loved going on trail（小路） runs. It was my favorite way to escape stress. So, when I was back in my hometown after a tough first year of my Ph. D. program, I thought a trail run was just what I needed. But instead of helping me relax, the run did just the opposite.
After I moved to the city for college, where my runs were on flat concrete paths instead of winding dirt trails, I used a GPS watch. When I went on trail runs again in the country, it constantly reminded me of the fact that I wasn’t keeping up with my usual pace. I turned my watch off, thinking that would allow me to enjoy my surroundings and find the peace I expected, but I worried I was underperforming. “Why can’ t I let go and just enjoy myself?” I wondered. But after some introspection（反省）, I realized why I was struggling—both on trail runs and in graduate school.
Going into my Ph. D. , I had thought that my solid undergraduate track record would set me up for instant success. To my surprise, I was wrong. I lacked confidence in my research abilities which I thought stopped me performing well and I constantly felt my progress was too slow. Other students’ self-confidence and their excellent results made me feel insecure. Finally, one day I broke down in tears in my adviser’ s office.
Then came my visit home: I was having trouble because I hadn’ t properly adjusted my expectations to the differences between an urban run and a trail run.
A Ph. D. is like a trail run: Sometimes you can run fast. Sometimes you might find yourself climbing up a steep, winding trail at a snail’ s pace. And that’ s OK. Barriers are unavoidable, and success looks and feels different on a challenging trail than it does on a smooth, flat path. Sometimes it’ s best to take a deep breath and do your best to meet the challenge.

思路点拨根据第二段的“but I worried I was underperforming”可知,跑步没能让作者放松,相反却感到焦虑。
思路点拨根据第三段中的“I lacked confidence in my research abilities which I thought stopped me performing well and I constantly felt my progress was too slow. ”可知，作者在学业方面差是由于自己对自己的研究能力缺乏 自信。
