Today is a full day1 for me as I have lots of work to do.  Fortunately I have a good partner to rely on2.  In my leisure I like to think about what I wanted to do.  I admire people who has enough time to do what they want to do and what they want to be.  Why can't I be one of them?  What is my goal in life, I asked myself repeatedly.  Never could I find the answer.

My goal ?

Today is a substential day. I have lots of work to do. Fortunately (*for me), I have a good partner. In my leisure time I would think about what I am I working for? do I work for? I admire anybody who have  has enough time to do what they want to do and to be what they want to be. Why can't not I  be them. What is my goal in the life? I ask myself repeatly. But what is the answer?   ~Your sentence is right, but it sounds better if written like this: But I can not find the answer. or But I have not found the answer. ~
