what should i do?

after handing in all da assignments and thesis, suddenly i lost my goal. not knowing what to do.... it seems like playing, eating, sleeping and spending money has become the routine of my life and yet this is not i want. what should i do? i just realized that teaching is not sth that i wish to do for the rest of my life. i wanna start some business but i have no one to help me. not wanting to depend on my parents, i did not tell them my plan as i want to give them a surprise. ai... really out of idea now... what should i do? someone help me....
