Be realistic about it.
Don't DM a lot of people at once. Focus on one person one day, wait a few days, and DM someone else.
Nurture relationships.
Don't kiss (give a link) on the first date. Do that later on after you've established a relationship.
Be real with people. It's easy to spot a salesperson in 2023.
It's good to have an avatar of your ideal customer/client. I don't mean an avatar like a picture. I mean, like a vision of the type of client you want to use your services. An expectation of who that person will be and what they will be like. Then you can focus on campaigns for those people exclusively.
