What 3 simple decisions changed my life for the better in the last 5 years?

We're often told about grand changes people make in their lives, but the tiny choices add up quickly I realized a few years ago that making small decisions proactively, like waking up early, cooking meals for the week, and setting aside 10% of my income for savings, set me off on a path that transformed my life.
Over the past five years, my daily routines and money choices have snowballed into some amazing benefits, like starting a podcast on productivity, being able to invest in a dream home, and gaining a sense of confidence and security I'm now wondering, what other small changes can people implement in their lives to set themselves up for long-term success?
What do you think is the simplest decision you've ever made that's drastically improved your life?
