Same goes for mahjong....as u ppl noe, usually mahjong play wif
$$...
N there's a sayin, tan qian shang gan qing(tok abt money hurt e
relationship)
Of cos, when cum to $ wise, it's serious business...but lose $ or
win $....u got to hav gd conduct....lose $ jus treat it as a
lesson, suay, bad luck, ppl more luckier den u!
Win $, u beri lucky, u heng, pther more suay!
Therefore whenever I play mahjong, I will play it seriously, but if
i lose, so be it...if I win, of cos gd lah....no point showin a
black face n spoil ppl mood rite!!!
A beri gd example wld be studies n exam....U treat exam seriously,
cos it's important to u, but when result came, u fail, so be
it...dun blame any1! But when pass wif flyin colors, of cos is gd
news lah! 
Bottomline is, I enjoy e process of e things i lik to do(play
mahjong, billard...etc...) At e end of it, it's jus a game, win or
lose does'nt really matter much! Wad impt is wad have u learn in e
process, did u enjo it?
Well, all e above is jus my 5 cents worth of views...no offence
thou!
