Take an inventory of your 5 closest friends. Now this can also include family members. Basically people you communicate on a regular basis.
Now you might not know this but estimate it by figuring out their current lifestyle.
So here is an example
friend 1. 50,000 year
friend 2. 35,000 year
friend 3. 40,000 year
Friend 4. 53,000 year
friend 5. 22,000 year.
Now you take that number and add it all up and divide by 5.
This will give you the average income of $40,000
Now look at your own annual income and 9 times out 10 you will be very close to the average.
So in order to increase this you need to get 5 more friends that make more money
Now I'm not saying that you need totally get rid of them as friends, but what I'm saying is that you need to seriously step outside of the box. Start meeting people outside of your existing circle of friends.
Start looking for a Mentor, participate in local networking events, Join the chamber of commerce or any other business type clubs. Start building the key relationships.
You will be surprised how this will dramatically increase your income. It's all about "influence" and getting new "access" to things you normally would not get with your existing friends.
