My girlfriend has tried her hand at blogging a few times and the staying power it takes is actually massive, so congrats on keeping at it for 7 months! I know when you first start you don't get any kind of encouragement so you need that passion that you mentioned to stick with it.
Luckily, for many who start out here on Steemit, you get a boost when you first come on and it really helps with that will power to push on.
