Spending more than one hour in the train, get to know new friends, learning something new everyday.
I think this could be expressed as a "trip".
I was exhausted day-to-day at the begging of this semester.
However I found out this exhaustion was part of a "satisfaction".
I think a true satisfaction is reached only if you try hard, get tired, but still keep going on and on.
My english is still immature, and because of this, it disables me to express some of my feelings sometimes.
I must study hard.....!
