Don't worry..Be happy.

So throughout my endeavors to write songs, I have discovered a few things.
Firstly:
When you write song lyrics, poetry, anything where you can be as subjective as you wish, Don't try too hard. If you try too hard to write something deep or original it will sound fake. When you create something artistic i.e, write songs, poetry, music etc. You are largely using your subconscious mind. I believe this is the part of your brain you use when dreaming. It is capable of expressing things in very unique ways. All you have to do is BE QUIET. Stop trying to think so hard and just let it happen. Trust me, if you have an artistic bone in your body then something will come.
Secondly:
Write about what you are familiar with. Don't try to write a song about something that you have never experienced. For example, if you are single and have never been in a relationship, don't attempt to write about a rough breakup, because even though you can probably imagine what it's like, the feelings are not alive and fresh inside of you. It will not be as powerful from someone with whom it is not firsthand. Now if you want to write about something far fetched that you have never done, like whale hunting or something, that is a bit different. lol
Next:
While it is perfectly fine to use songs as an outlet for emotions, be careful that you are not only writing sad songs, or angry songs. If you intend to make music for a living you should try to write a wide variety of songs in many different moods. And for marketing purposes...it has been my amateur observation that happy songs sell. In todays frustrating world, people want a bit of optimism. Anybody can write an angsty rock piece, but not everybody can write an upbeat, expressive, happy song. One person who is great at a balance of different moods when they write is Adam Young From Owl City. Try it sometime.
These are just a few of the things I am learning as I go. If any other aspiring songwriters are out there reading this, I hope it helped. :)
