Who sets the standard for what you achieve or accomplish?  Is it you? If you are living to someone else's standard, then what is your standard? 

Living to fill the expectations of others is an empty cause.  Still, we should have a high personal standard for the quality of our work.

Sometimes others have low expectations and we feel so good when we grab that "low hanging fruit".

So the trick is identifying the value of the expectations have of you?  Is it too low?  Then set yours higher.  Is it unrealistically high? Don't get beat down trying to meet lofty expectations.  The key is having the ability to judge the value of the expectations!
