no one can make you 150% happy and the unrealistic expectation s

translates into disappointment and ... even hatred.

People often feel they "deserve" so and so, and when that circle starts, he/she eventually can become self-centered, thinking more about "take", rather than "give". This can easily destroy a marriage or relationship.

Let me switch the gear a little bit to the philosophical side:

How do you define "successful"? You mentioned this word again and again, but it seems to me you are equating "successful" with "wealthy". Don't get me wrong, money is not a bad thing ... but at the end of the day, why are you here in this world? what truly makes "a successful life"?

You don't have to answer this, but I hope it will make you pause and think for a few minutes.
