I found a fitness coach online and he is legit. He charges $150 a month, which is way too much money for a teen. I'll never work out with him in person, instead he sends me workouts and I do them. This makes me think that $150 is too much for a personal trainer. I make about $500 a month and work only during the summer. How much should I pay him, if at all?

Hi. I guess I just need some support? I'm going into my junior year of highschool and I'm scared. The last 16 years of my life have been easy, and as a little girl I always told myself that I would make it to college and be super successful. Now that I'm older, I realize that college in expensive, and that my running and academic talents aren't as impressive of others, especially since I go to a big school. I just find it do overwhelming that the easiest years of my life are over and that I'm going to be an adult soon, and I'll have to be completely independent. I just wish I could be a little 9 year old again who could listen to Hanna Montana and never worry about her looks. I just can't believe that the easiest years are over. I find it scary that after I graduate, I'll need to decide what I do and pay for everything all on my own. I have a summer job as a lifeguard but that isn't gonna cut out the costs of college. My parents won't even be able to help with college because they're getting divorced when I move out, and they're swimming in debt as it is. Can I get some guidance? Thanks 

I'm trying to qualify for a certain track meet. You have to run a certain time in a certain event to go. For example, if you run a 400m in 68 seconds and then you get to go to that meet to only run the 400m. What event should I go for?

-400m (quarter mile), where me personal best is 77.7 seconds, and I must get 68 seconds to qualify

-800m (half mile), where me personal best is 2 minutes, 58 seconds, and I must get 2:38 to qualify

-1600m (full mile), where me personal best is 6:25 minutes, and I must get 6 minutes seconds to qualify

Or

-3000m (almost 2 miles), where me personal best is 13:54 seconds, and I must get 13:20 to qualify

I only need to qualify for one race, and I only need to run the qualifying time once. Which one should Itry to qualify in?

I bought a darker shade of face powder to contour with, but the shade is wayyyy to dark. It looks horrible. Is there a way to make it lighter or to put on over it to lighten it?

I need to know if there are any universal beliefs, values, and ethics in literature that are of interest or concern to all cultures and societies across time and how they influence behavior for my midterm. I need to be able to explain what it means, and use one example from these stories: Enuma Elish, Epic of Gilgamesh, Code of Hammurabi, The Upanishads, The Ramayana, and The Bhagavad Gita. I also need another example from the stories The Illiad, Julius Caesar, and The Aeneid.

Just wondering. Anything good happen? Bad? Exciting? I'm just bored someone answer.

Can someone figure this out for me?

This is Michael Jackson's song "this is it" backwards. I don't know what to make of it. Here's a link to the lyrics:

I'm not sure what he is trying to say. Is he alive and coming back? Alive and not coming back? Dead? (follow up question with the dead- how did he know he was going to die at that time?)

Thanks
