Enquiry about my business and money

Hi, I was born on 1977 october. I have a difficulty to decide whether to go on with my construction company or just sell it off to other people and get 1 time money. As I cant really focus with it. I hold on to the company since 2010 and i've gone through tough time and obviously I have not gain so much from the business. I cant seems to see any good future from it. Should I just let it go?

Thank you.
