Thank you for a very informative post. I am in that situation of deciding what niche I should occupy. I have lots of life experience and stories that I am sure will resonate with certain people but there is that nagging doubt, should I share all that stuff? Reading your post has helped me reach a decision. Followed and upvoted.
Only way to find out if it's a good idea or not is to do it :)
You are right! Time to move ahead.
