Mind can never be satisfied!

I'm writing,because,surprisingly,i'm feeling this! Mind really not be satisfied ever! When i came here with the dreams in my eyes,atleast someone would pay for my work,atleast i would also have my own money,my own name! I got my first salary already,still i couldnt show that happiness which i should be. Now i have my own name,my own money,still my mind wants more,i think,its never ending desire and expectation!really surprising! But i wanna be happy truely what i'm,what i achieved,but i cant! May be this is my psychological problem or human mind is like that. Who knows?
