As humans, we decide what is acceptable by soaking up the influence of our surroundings. As such, most anyone you come into close contact with, for example, your parents, professors, and close friends exert a large quantity of influence over you and your decisions; their thoughts, ideas and opinions on things have an impact on what we believe is possible in our lives.
On a positive note, your inner circle will exude a feeling of belonging and well being. But on the other side of the coin, there is resistance and even envy in some cases. There is a well-known experiment involving monkeys that illustrates this idea powerfully.
Then they removed one of the original monkey and added a new monkey to the group. Although accepted by the group, as soon as he spotted the bananas and went to retrieve them all the remaining monkeys pulled him off the pole - even though this time there was no water hose. They had been conditioned to believe that climbing the pole equaled pain so they were "saving" the new monkey from harm.
Soon even the new monkey stopped trying to climb the pole. Eventually all the original monkeys were replaced one by one until none of the monkeys in the enclosure had witnessed or experienced the actual water treatment and yet none of them would make any attempt to go up the pole and get the bananas.
What's the point?
Surround yourself with people who strive for more and that are in the possession of more. Keep your inner circle filled with people who believe in the same quality of life that you do and that may even have a higher vision of life so that they will ultimate have a positive influence on your life and you will then aspire to do more and be more. Remember, your network is your net worth!
