Simplicity to improve your life
This list is inspired from an article titled 10 Reasons Why a Simple Lifestyle Can Boost Your Happiness. The article tells what simplification can do for you. My list tries to offer some examples about how to get started/
1. Simplify your career
While most people seek to move up the corporate ladder, each promotion will frequently come with more stress for having greater responsibility. Triple the work and triple the stress for twice the pay may not be such a great tradeoff.
2. Simplify your relationships
Don't keep score.
3. Get a dog
Great for grounding and time spent with your dog is probably time your mind isn't racing.
4. Buy fewer items and get rid of items you don't use
This is a sort of prioritization which comes with understanding yourself. Personally, I don't need a lot of clothes but having tools makes life easier for me as an example
5. Spend less than you make
Life is simpler not having to worry how you're going to pay for this and that, having no margin for error.
6. Simplify your diet where possible
The more meals you can eat from food purchased at the edges of the super market that has no ingredients, the better off you'll be. Every single meal being this simple may not be realistic but I think most people have room to improve.
7. No envy
Don't pursue what other people want for themselves.
