Had laksa for lunch... Nthing fanciful...
Basically depending on the various field, ur workpath will be
slightly different... apart from the usual work+upgrade...
Design/art/music as we know requires portfolio...
Finance/econ also requires portfolio of some sort, aka good
resume with workings in big financial institute/banks/audit firm
etc...
Engineering requires knowledge... as long as u have relavent
working experience, the rest all counts on knowledge...
Marketing/sales requires result, good track records 
still got alot others I guess...
