I was sitting in a chemistry lab class during my first year of university，nervous about the experiment we were to perform.I grabbed a pipette （吸液管）and，as I feared，my hand started to shake.The experience was disheartening：I was hoping to pursue a career in science，but I started to wonder whether that would be possible.I thought my dreams had crashed to the ground.
   I was a boy born with brain damage.My family managed to find good doctors where we lived，in Leningrad （now St.Petersburg），Russia，and I took part in clinical trials testing new treatments.Shortly after my first birthday，I started walking and it became clear my intelligence function was unaffected.So，in some sense，I was lucky.Still，I couldn't do some things growing up.Both hands shook，especially when I was nervous or embarrassed.My left hand was much worse than my right，so I learned to write and do simple tasks with my right hand，but it wasn't easy to do anything precisely.
   As a teenager，I faced a lot of bullying at school.Feeling alone，I joined a study group called "The natural world".I thought that getting into the world of animals would keep me away from people.That's how I came into the field of biology.At university，I enjoyed the lectures in my science classes.Many lab tasks proved impossible，however.As I struggled with my mood，I read a book about depression.From then on，the physiology of mental disorders became my scientific passion.I looked into what was being done locally and was excited to discover a lab that did behavioral experiments in rats to study depression.
   At the end of my second year，I approached the professor of the lab to see whether I could work with her.I was afraid to admit I couldn't do some lab tasks.To my relief，she was completely supportive.She set me to work performing behavioral experiments for others in the lab with the help of colleagues.I loved the supportive atmosphere and stayed there to complete my master's and Ph.D.
   I've come to realize that my hands aren't the barrier I thought they were.By making use of my abilities and working as part of a team，I've been able to follow my passions.I've also realized that there's much more to being a scientist than performing the physical labor.I may not collect all the data in my papers，but I'm fully capable of designing experiments and interpreting results，which，to me，is the most exciting part of science.
