how do you see yourself?

in my quest of my passion and happiness in my profession, i am undergoing numerous exams and interviews with different companies. i have encountered several odd questions and there are challenging and funny ones. but the most common questions that i have encountered in almost all of them are these:

how do you see yourself now?
how do you see yourself in five years? (or in 10 years)
what are your goals in the long-run?

if you were to answer these questions, how would you approach them? or how can you express yourself without sounding too laid-back or too intense in life? (i am also asking for tips on how to relax and how to appear as accommodating and pleasant as possible, you can add them all here!)

sometimes, it's hard to face tough recruitment since they are all a matter of perception and first impressions, 'coz their are seldom 2nd interviews on the same person. so you really have to be careful with what you say otherwise you might blow everything in the wrong direction - which I presumed is something you don't want to happen.
