Hi M. M.!
I don’t think you have to post every day to succeed. Once a week is good.
What you do want to do is focus on providing value for your reader. You do that by deciding what you’re about. That is as simple as completing this sentence:
Every ________ should _______.
Every man should get married.
Every teenager should learn good manners.
Every salesperson should study psychology.
You fill in the blanks with what you want. The first blank is your target reader. The second is what you believe he or she should do.
If you want to build traction, pick one topic and go deep with it. Stick with it for 30–60 days. If it fails, move to your next most passionate interest.
I wish you the best! Let me know if you have more questions.
