I often recommend to switching from a consumption mind to a producing one. Instead of looking for the next Netflix show that will cure your boredom, or for a person to entertain you, make something. Of course, this is easier said than done. Boredom doesn't disappear because you decided to do something.
One issue is that boredom is developed over a long period of time, to the point that it becomes a habit. Once you decide to do something about it, expect it to take just as long to part with it.
You can still watch your Netflix show, but make a schedule for your boredom breaking habit. Every evening at 6 write for 30 minutes. Try to run a mile in the morning without any earphones. Practice a musical instruments once a day. Read a book for 30 minutes a day. Nothing to drastically change your lifestyle, but over the course of a month, these habits replace your boredom.
