If you're new post an introduction. Include the following:
Your name
Name of your business
Your current bottleneck (problem you're solving)
Your 5-year goal with your business
Types of business owners you'd like to connect with (e.g. "I'm looking for 40+ year old business owners that have experience with hiring top talent).
A question you have for the group.
You may or may not get a lot of responses, it depends on a lot of factors. It's ok if nobody does, it makes it easier to recognize you when you join the workshops and the meetings. Getting likes on these threads is not important.
Just remember, when you're a part of this group in the future, try to like and comment on posts that interest you. It helps people to feel seen, even if it isn't important to get likes on a post.
