I agree.You can't "side hustle" insurance.
It's a full time gig.
Go all in or dont do it. Selling insurance is a business, and needs to be treated as one.
Quit your job, and invest real time and money into insurance, and build your business. If you do it any other way, you will burn out, and end up quiting and/or losing money. You will never take it seriously as a side hustle, especially if you have a family.
