Try as I might, I don't have an answer for that. For me, to blog is to just write/post/vent/inform/encourage and so many more things. I know some people have one certain focus, one certain theme that they write about like reviewing cosmetics or teaching people how to make things. I can't seem to focus in on one topic like that. My mind rambles from thought to thought and I am interested in so many different things, how could I possible choose just one? There is such a vast array of things to write about that just happen in a daily life.
So I guess my "purpose" for this blog, while it's mainly for me to ramble out the things I think about, would be to hope that even just one person finds something here that touches them, that inspires them, that makes them think, that gives a little bit of encouragement or even gives someone a little giggle. Maybe makes them say "haha I'm like that too." After all isn't that what we're on this earth for? To touch the lives of others and to make a difference to someone, somewhere.
