My system is to interact and support others as much as I can. I’m no expert, but what I have learnt, I like to pass on. I think it’s the teacher in me.
I started my own Facebook group for that reason. I am growing a lovely little community.
I use this for all social media. If you comment I will comment back. If you follow I will check your stuff out. If I like what I see I will follow back.
Building genuine relationships is my go to system.
