Why I need one job instead of two

I have a B.S in chemistry, and a MBA with a concentration in healthcare management, you cannot tell this from the paycheck I will receive from my August work shedule. I am currently working two jobs to pay off credit card debit ( mostly from school expenses) and my college loans. In August I will spend time at home only one day because I either will be working or traveling. Thank God for the traveling because I will be able to have some kind of fun, but will all this when can I jobhunt.
