resently, my friend began to work really hard. well, i guess i missed out something. i thought he was good enough, but he didn't agree with me at all. he thought he was never good enough. he said he felt a strong need in his company, because he was the only one good at this technique. he felt like it was his responsibility to help others so they could have a few time for other things. he also said, he felt he had spent 26 hours in his office and there was no time for family and friends any more. i asked him why he didn't take a holiday and learn to enjoy life sometime. it's not possible to stay in office all the time. besides it was impossible to finish all the job. i knew he also wanted to play with dogs or fishing, i saw the desire in his eyes and i asked him for a reason he said he felt guilty towards his colleague, so he just did all the work.
