Sweetie, have you ever heard the expression, "A watched kettle never boils."
If you are so fixed on seeing how many posts you have, then it will go slowly for you.
Try not to pay attention about the number of posts you can get in a day. Ignore it, don't even look at it and before you know it, it may not be today or tomorrow, you will reach your goal of 300.

Just post away without even thinking about it. Enjoy reading other peoples threads and post away.

I think in the two months you have been here, it is awesome that you already have, what, 250 or more posts. I didn't reach that until after being here for about 6 months or more.
So please don't worry about it okay...You are doing good

Also, it isn't how many posts a person has, it's just the enjoyment of getting to know you that makes a difference.
