learn to say NO when people rush you!

poor guy, no knowledge and no guidance, umm, how to do? perhaps u should learn by 'mistake'..

but of course, ur boss will scold if u make mistake.

What to do.. if u really duno how to do that, u feel the tension then apply elsewhere lo.. let him hire the more experience guy and let the new guy settle it by himself..

or if u plan to stay here. then u have to open ur mouth and ask, colleague, boss, senior.junior, or even ur relatives/friends for guidance...
