It's how we learned as kids. We watched our parents walk, and then we took our first step. We listened to them talk, and then we said our first word.
It is all too natural for us to learn from others and to adjust to our environments. Even 20, 30 and 40 years later, we still naturally do as others do.
Don't believe me? Do you find you dress differently in different settings? Do you find you act differently with different friends? Do you act different in MacDonalds than you do at the finest restaurant in town?
Our environments have a HUGE influence on our attitudes, our worldviews and ultimately, our actions.
Take a serious assessment of what your surroundings are today. Where do you spend most of your time? What colour is the room? Do you take the time to walk outside or are you stuck in your desk? Who do you talk to the most in a day? Is she a happy person, a sad person, an idealistic person, a creative person? What do they do all day? What do they wear?
You are your environment. Please choose it wisely.
