Decisions regarding feelings

One of the hardest and most difficult things in life is making decisions. I'm not talking about whether you have to choose between a green or a blue shirt but about the decisions which will have effects on your life. And it gets even harder when other people are affected by these decisions.

And when it comes to feelings your whole world may turn upside down.
For example at the very beginning of any relationship there is often this one question: Should I follow my heart or think about it more intensely?
I guess I don't have to mention the whole bunch of other questions which start filling up your head until you are just about to explode. But in the end it's quite funny because if you're a teenager and you face such a situation I bet you'll laugh like hell when you're 21 or older because these things seem so naive, superficial and hilarious then.
I know lots of people who loved someone and a few years later they couldn't believe how superficial they were at that time.
Knowing that you'll laugh at yourself later makes you want to avoid such a decision because saying the three words to someone means you’re making a promise.. and if you know that you won't keep it anyways you should simply avoid saying them.. and it’s not because you’re moody but because you simply grow up and the way you analyze and interpret things totally changes (that's if you're not a hopeless case).
So, giving someone a promise you can't guarantee for life is simply stupid and irresponsible.
To make it clearer, let's say: Two people reveal to each other that they love each other and let their emotions run wild. Two years later (and they should have become more mature by then) one of them or both of them notice that this isn't the picture perfect they had in mind so they split up. If both came to the same conclusion then it's simply fine but if it's only one part who did and the other one is still falling for the other one.. Well, then it comes to the cruel and unpleasant part: One gets hurt. Of course he/she won't be lovesick forever but even if it's for a while it still hurts and there wasn't a real reason to let it come that far.
Now one could say: You can be 25 years old and find out two years later that you are not meant for each other. That's true. But in this case it won't be because you hadn't made up your mind about what kind of personality you want but because it took time until you've gotten to know each other very well and you started seeing things you didn't see at the beginning.

And I guess everyone knows how moody and capricious teenagers are.
By the way, I know I'm still a teenager too (only 2 years left to say bye bye to that) but the knowledge that most of your views will change makes it easier to accept that the time hasn't come yet to experience all the things.

All in all, I guess what I teenager like me can do is: Enjoying his life surrounded by his family and his real true friends, studying/working hard to achieve something later (have to work on that :$) and watching how life goes and develops so he gains some experiences from the surroundings!
