You must focus on your post destiny not your post length.
I don't know what you mean by post destiny. Did you intend to say post destination or you are maintaining post destiny? Pls you can return and clarify me pls.
To make a good post,you also have to speak in the right tone of voice of the readers. There are so many educated people here,would you speak to them in the same tone of voice as u would speak to your 5-year old daughter?
(Unless u were seriously weird).
How will one know who is 5years old and who is a professor. The best thing to do is to be polite generally even in the offline world. Speak with meekness to both 5years old and 50years old and your spirit will be at ease with everyone. Though some people may want to ride you but you have to resist.
