Don't start 20 new habits... at once...

💡If you don’t like where you are currently in life and want to completely transform into a new person, you don’t want to start twenty different habits at once.
I mean, you don’t have to
· start meditating,
· start exercising,
· quit eating sugar, etc all at once. That’s the shortest way to overwhelm and misery.
👉But have you ever heard of keystone habits?
Charles Duhigg in The Power of Habit calls them the “small, key habits that spark a chain reaction.”
By the way, a keystone is a central stone at the summit of an arch, locking the whole together.
Think of them as the first domino. Once it falls, dozens of other habits start aligning automatically.
To give you an example: When I wanted to get in shape and build endurance, I focused only on Running 15 kms a week. That’s roughly 2 kms a day. When I mastered that habit,
· I started lifting better,
· drinking naturally more water,
· started having better metabolism. (One keystone habit. Multiple positive outcomes.)
Recently, I wanted to improve my sleep quality. So, I focused only on not sleeping with my smartphone. I enforced some controls only to get that one habit achieved. The moment I stopped carrying smartphone to bed, I started sleeping better. Not just that,
· it improved my running speed,
· it lowered my resting heart rate,
· it cut the need for me to take a nap during the day,
· I feel less need to eat junk snacks during the day and so on.
This is the ripple effect in action 🌊.
One simple habit doesn’t stay contained—it radiates into other areas of life and work.
And the best part? You don’t need to overhaul your entire life. You just need to find your keystone habit—the one that triggers a positive ripple everywhere else.
