Maslow's Hierarchy of needs is a pyramid model that depicts what people are motivated by. It looks a little something like this:
realizing personal potential, seeking personal growth and peak experiences
4. Esteem Needs
achievement, mastery, dominance, respect from self and others
3. Love and Belonging
friendship, intimacy, affection, sense of belonging within a community
2. Safety and Security
protection from elements, order, law, stability, freedom from fear
1. Biological and Physiological Needs
air, food, drink, shelter, sex, sleep
Our needs vary. Our appetites for food and sex are different from person to person. Our idea of what a home is depends greatly on what we're familiar with; what we grew up with. Some people spend one day a week with friends and their social meter is exhausted, while others can spend several days a week with their friends and barely tire out.
Our subconscious associations play a key role in creating our current desires. The solution is to understand your associations in order to help you understand and master your needs. For example, if you grew up in a home where your parents had a wide social connection and enjoyed the frequent company of their friends, you may place a stronger value on time with friends and therefore require more time with them than the average person.
Now, let's say that you have a busy work schedule that rarely let's you have time with your friends and you feel like your social life is lacking. You can try to adjust to meet this need. For example, you can reexamine your schedule to see where your time can be better managed in order to meet this need. Or you can rewrite your subconscious script. Two key ways to do this on a conscious plane is by fully expressing appreciation when you do have time with friends rather than regret that you don't have as much time as you'd like, and by rewarding yourself when you are doing things that are good for you even if they pull you temporarily from you social circle.
There is a fine line between understanding your subconscious in order to create new limits for yourself, and brushing your needs aside. This requires true honesty on your part in order to establish the line between when a need is intrinsic to your person and when it is something that can be altered for your greater good.
