Well, I'm not very sure myself, but if I were to choose any of what you have stated, then it's definitely passion more than the rest. I lost my will to learn even since the school days! Financially independent? I'm far too financially dependent now... Ermm... do you really think I eat that much? I'm only 50kg after all... My first pay check went instantly to my D70, no chance of smelling the cash... Of course!
Chai = 1 bag of cement? I can carry that! ..ahemm.., do you now find what you're doing challenging? No longer suffering from boredom?
No doubt is not heavy to carry at all! Nope, other than shit loads of jobs, I don't really find it challenging anymore, so I'm still suffering from boredom...
