Her entire comment is worth reading but I wanted to share her very last thought:
“Networking, done well, is an investment.”
Think about it – if you have $100 and you invest it in something relatively safe you might be able to get, say $120 out later.
Is later tomorrow?
NO! (usually not)
You might have to wait for a year before you can get the increase.
Usually investments take time to mature.
If networking is an investment, when do you think you can get the value out of it?
Perhaps not until next year.
You need to start before you need to pull your $120 out.
