Sit in silence for 15 minutes. Don't try to meditate, just sit silent no phone no tv no music no moment.
For 15 minutes and just observe all the thoughts you mind randomly comes up with.
Watch how uneasy it is for most. You don't realize how little control you have over your mind until you try this. Once you realize how hard this simple task is for you you'll realize why you need to practice this regularly to take back control of your mind.
It will change your life
