You are influencing your future self
You cannot control your thoughts, and you are always influencing them.
Call to mind any recurring thoughts or topics that have been on your mind lately. They are certainly not random. They are more than likely a product of the people, conversations, media, environments, books, podcasts, and energy you have been around. Either recently or in the past. Each thought comes spontaneously, yet not independent of what you have consumed in your lifetime.
When you were young, you had very little choice about what you were exposed to. You now have more choice than ever. In your car, in line at the store, on the device you are looking at right now, reading this. Each thing you take in is changing you in one way or another into your future self. What are you choosing to contribute to or detract from your well-being?
What if you approached each moment of your life as an opportunity to positively influence your future self?
