30 years old, I still have nothing to do, in a mixed day, how should I choose

Now I am 30 years old, and I have been married for more than 3 years, and my daughter is almost one year old. I do not know how to choose, looking at the buying car of your own peers and buying a house to buy a house, but I have nothing to do. Now I do not know where I do not do, I have worked hard, but still do nothing. Is it not enough for me to work hard? I hope you will give me some advice.
