I want to ask anyone to enjoy jobs

I want to ask anyone how to enjoy jobs. Today I understand that almost jobs I did, I didn't feel it's a interesting job. In other words I didn't feel to enjoy to work. 
It's not good for me I know, but I don't enjoy to work. I feel so sad myself because we all working is most part of our life. It means I spend the time for boring things. I can't endure this situation. 
Many books and persons tell me it your problem, and the person to solve is you only. I should think about my life seriously.
