“If you are planning for a year, sow rice; if you are planning for a decade, plant trees; if you are planning for a lifetime, educate people”
Well, your networking results probably won't take a decade but it will take longer than just a couple of visits.
If you're networking for business you're in it for the long term and you never know when you'll see the benefit of your networking.
Very rarely will you go to a networking meeting and instantly get business. Yes, it does happen - I saw it happen for a printer some years ago. He attended his first meeting and got enough orders to pay for his membership for the year!
Networking takes time. It takes time for people to get to know you. It takes time for you to get to know them. It takes time for them to either really understand what you do or to get to a point where they're ready for your product or services.
It's one of the reasons you need to invest time in your networking - don't just go along a couple of times and give up because it's not working, go regularly - every week or every month.
You might be surprised at the results you see from your networking, months or even years in the future.
