Seriously...as has been said...get a f@#king job. You won't have time for dicking around in the car...you won't be bored out of your mind, and you'll get MONEY.
Since you aren't doing anything scholastic, you should get a job and work your way up. I'm not $h!ting you here...I've been promoted twice in two summers at Qdoba. They pay well, and as long as you do the job you're paid to do to the best of your ability, you will get promoted.
See, I started at 6.50, got bumped to 7.50 this summer (you're not supposed to get more than a 4% increase...but hey they loved me) and upper management liked what they saw and transferred me to an underperforming store in need of good people, promoted me, and are in the process of training me for shift manager which will start next summer. I don't know a manager who makes less than $10. Also, since I've been transferred, customer satisfaction has more than doubled at this store, tips went from nonexistant to filling the tip container, and I have been told by upper management that customers are specifically telling them that I am "fantastic" and "extremely polite and helpful." Now I couldn't care less about those indecisive morons who don't know the difference between a salad and a quesadilla, or don't want the medium salsa "because it's green," but if fronting nice to the customers gets more money in the tip jar and the attention of upper management for promotions then hey I'm all for it. Why? Positive attention equals more $$$ and more hours...in turn leading to even more $$$. I made overtime this week. My upcoming paycheck will be for over $500. Somehow, I can afford $700 fraternity dues as well as driving a 15 mpg premium requiring M-Class as well as spending way too much money @ A&F and bluefly.com.
You CAN have your cake and eat it too, you just have to work a little for it.
