“Habits are the compound interest of self-improvement.” -James Clear
As Zeno of Citium said, well being is no small thing but made up of little steps.
Getting up consistently so that your circadian rhythm is not screwed up.
Reading every day so that over time your knowledge base grows.
Exercising every day, even if you are tired.
Investing through your retirement plan at work every pay cycle, no matter how you feel about your job or the politicians or the economy in the short term.
Consistent investments (of money or time) produces a huge non-linear growth curve over time. You won’t see a change in a day or a week, but others will start to notice after a month. After a quarter you will notice, after a year your ex will be jealous, and over a few years of consistent allocation, of sticking with the good habits, the world will notice.
Consistency is the key.
