What to do with $10

Hello everyone. Longtime reader, and first-time poster. I took the fifty4free.com free $50 for Party Poker a week ago. I finally received the $50, and unfortunately, squandered away $40 by not following the advice of sticking to the micro-limits. I have $10 and would like to know what I should do, whether I should stay at the micro tables or try my lack of luck in a tournament or 2. I know I may get berated for my disastrous decisions with my free money, but hopefully the help I may receive can help me get back that money with interest. Thank you for all the help.
