Harsh truth here.
Some LinkedIn users only engage with you when seeking new opportunities.
If I don’t have a relationship with them, I am not eager to help them.
Online networking is like offline networking.
It takes time to build a relationship.
So…don’t be active on LinkedIn only when you have needs.
It is too late.
Spend time having a conversation with your contacts regularly.
The best time to network is when you don’t need to network.
