I'm scared because I don't know what God wants me to do?

God has given my talent in many areas (not boasting) and I look forward to the future so much when i can use them to glorify God and make a living at the same time. I'm in college at the moment though and looking through certain professions, and they all seem so far away from me :( I love hard work, when its enjoyable, i even enjoy doing my AS levels at the moment which is strange because everyone i know hates college because its so hard. Every profession i look into seems so hard and stressful and makes me think theres no way i'm going to enjoy life doing that :( I feel that if i don't find out soon what i want to do, then the talent that i have will go to waste and i'll end up just floating around doing jobs that so aren't me :( Everyone says that you will know what God wants you to do, but i have no idea, and i can't stand all this waiting, i feel like time is running out :( Please help me :(
