I know that I complain a lot, especially about work. But oftentimes, even during busy busy days, I feel content and happy because I was productive that day. It's not really about being too attached to your work, but more of having that sense of accomplishment. It's about knowing that you aren't just being idle and useless, it's about knowing that you were able to share something within you by giving your best in whatever you do.
Cheers to the job that gives a P100,000++ bonus. Hahaha. I kid. =) (But only about the bonus. Everything else, I am being serious. Swear.)
