People always misses the old times but did not treasure the present moments, or that's just me. I missed having lessons as well as disturbing my classmates. Those environment without politics or that much of two faces people exists. At least there are people I could trust. 

To me coping with monetary stress (having to balance my money to every single cents), insufficient knowledge comparing to most of my colleagues as well as making sure that I don't do or say anything that makes people dislike me really stresses me out and makes me really mentally tired. 

All I could do to cheer myself up a little is to search for nice scenery photos. That makes me wanting to go on a short gate away or just go somewhere else rather than staying put. Or eating really nice food after work or on my off day.
