Welcome to Steemit!
Don't worry about not having a direction for your blog yet, we all go through that. The important thing is just to start consistently writing and it will soon take on a life of its own.
If the quality of your comments are anything to go by, you've got a lot of good stuff to share, so just start writing and see where it goes.
See you around. :)
Thank you for the words of encouragement. I shall keep that in mind, consistency is key :)
