Figure out your interest and have passion in the things you are doing. Be patient and step by step. No matter what you do, put int effort, take routine work serious and don't assume it is not challenging enough. Then gold will alway shine!
whichever industry you will work for, you must know where your uniquenesses come from.
just as rumours fly around, working in a big industry (IT, finance,engineering) will actually make it even harder for you to excel and to set you apart from the majority.
so besides your fundamental qualities, you better have to sell your distinguish parts that few of your competitors could find in common to those critical adcoms.
