a little bit tired

it is saturday today , we are allowed to have two days for rest -today and tommorrow,but there is always somethings need me to go to my company , today I went to there at 9:45 am, and when I came back it was 9:00 pm, I have many thing that I haven't finished in my work, although I spare much time in work , the efficiency is always low, I don't know why and I feel a little disappointed by that . although I feel tired ,fitigue is not the point , I mean I don't care much about whether I become tired or not ,what I care most is that I am losing my free time , you know ,without enough free time ,I couldn't read the books I have bought ,I couldnt go to play basket ball, my chance of meeting friends and strangers will becoming little and little. I live here alone ,I am not young now, I really want to make my life colorful ,but my job make me sparing too much time in the company , it is a little sad anyway .
