Who you spend the most time with matters. By spending time with them, you are taking in their perspectives and values; and they you. Your reality lens folds those perspectives in, and you will adopt them as a part of your reality.
If your reality is filled with limitations and scarcity,
if you find yourself valuing or justifying resources toward property over humanity,
if you believe in punishment over reform,
if you feel more support around taking a break over taking risks,
look to see what sort of conversation is happening around you. Give it an honest audit.
You can read the most inspiring books, listen to the most elevating podcast, or hear the most powerful motivational speaker that gets you high and revved up.
If the words and actions of those you hang with most suggest that your head is in the clouds, that becoming great is for the lucky few, that your thoughts are radical and impractical, or make you ask yourself how are you even going to do that, then those hours put into motivating and inspiring yourself will be met with a critical choice to make. Which way will you lean?
