If I had to pick, one thing I aim to do each day, it would be this.
The reason this is my daily goal is because having a mind clear of unwanted thoughts, clears your path to live on purpose.
I believe every person should aim to achieve this, because I believe when you do, you feel more at peace, have less anxiety, and sleep better.
All of which adds to a healthy lifestyle and being able to live each day with fulfilment and joy.
