I don’t think it’s a secret. The way to get better at relationships is to engage often with those you want a relationship with.
I’ve read that the best leaders will send a message three weeks after first meeting someone, and then on a seasonal cadence there after. Each communication delivers some value.
How much value can you bring to someone else over an extended period of time?
How many people do you want to be delivering value to?
Interesting questions. I may try these ideas with some people I’ve recently connected with. I’ll try and remember to share back with you once I learn more.
