My job

Now, when someone asks me "What's your daily work?" or "What's your job," I used to say it's a long story. In fact, what I do is really very cumbersome which often puzzles me. What do I really want, pleasure, experience or just a job?
People often say when you are young, some much work can develop qualities and may be prosperous for you in the future. But I don't know whether it includes my present situation. I'm tired!

I've corrected some punctuation, capitalization, spelling, word tense and word selection.  What you've written is understandable, though.  Just keep practicing!

Many difficult jobs do build character (always through adversity) and offer prosperity (but almost never in the beginning).  Nothing worth having comes easily.  Some jobs don't offer a bright future.  We call these "dead-end jobs."  A dead-end street doesn't lead anywhere, it just ends.  Only you know in your heart which type of job you have.  Even if the job does offer prosperity in the future, working it for a year or two may be enough for you to know that you don't want to do it for the rest of your life.  If this is true, change jobs!
