Come on man, don't complain ! You are like 20 now right ? So you work for just 2 years now.. ? I've been working since the age of 12 and since my 14th had to give 50% to my parents for the household.
Not all jobs are easy and some people just are not so priviledged to have the brains or the luck to come higher up. I don't mind some heavy work at times, I won't complain about it even though i may not like it. I have done some shitty jobs myself. Think of cutting frozen cucumber into pieces in -7 degree Celsius conditions with nothing more than rubber gloves to keep your hands from cutting and freezing. Everyday about 70 crates of 25 kilo went through my hands. I hated it allready after 3 days or so but served out my 3 months contract, some colleagues with me on this same time were all unable to serve it out due to health problems or lost fingers !!!
The morale of the story, don't complain and work. If it's not nice work, then try and make the fun yourself by means of good jokes and stuff, as long as it doesnt delays the job.
