If you turn back time to the day you were conceived and instead of being left on the planet, you would have been taken by aliens to life with them, even before your mum knew she was pregnant, the world would be different in a countless number of things. Some smaller, some bigger.
Every single life on this planet has a huge impact on the current world, and on the future world.
The impact is unavoidable and not up to you. It’s there just because you exist.
What kind of impact you have is completely up to you though. It’s the amount of all the small and big decisions you make. Every day, every minute, every second. What decisions you make is your choice. You can choose which impact you have on this planet.
