How far east can you go before you're heading west?

Do you ever feel like your life is bipolar? I often find myself thinking, "Wow, everything was great, what happened?" It boggles my mind how things can be going great one moment then completely horrible the next. The world is funny that way.
I have experiences like this all the time. For example, I could wake up and be having the worst day at home, my parents are yelling at me, I don't have any socks, or I drop my toothbrush in the toilet. Then when I get to school it is like none of that ever happened. I get to school and I am the same "happy guy" that I always am.
Or it could be completely opposite. My day could start off in the most amazing way, such as finding $20 in my pocket, ect. But then when I get to school I discover I failed the Government test that I thought I did so well on.
I have learned through these trials that I have faced, that you just gotta go with the flow. I have learned that whatever happens happens and I have no control over how things will turn out because no matter what I do they are always going to turn out the same way.
So here is my advice for the day... Go with the flow, even if you really want things to go a certain way. Just remember that life is what you make it, you can focus on the good or the bad.
