Why write?

1. To show what could be
2. Art is the lie that brings us closer to the truth (increase understanding)
3. Simple escape from this world
4. Strengthen our mysticism
5. To help people survive their lives

Are these reasons actually worth writing?

Currently I only write when in a really bad mood and wanting an escape beyond the reading of other books. I'm not in that bad of a mood often enough.

I suppose these are worthy reasons. Provided I can remember them.

Writing rules
1. Something hidden from some other character in the book that isn't hidden from the reader
1a. Striving towards justice
2. Something hidden from the reader
3. An escape
4. Something beautiful combined with hardship and injustice (I forget about the beauty part.)
