Once in a while, go to natural places. Away from city & crowd. Towards mountains, forests, lakes, beaches.
Going to nature often is a wonderful experience.
Especially, if you’re someone living in concrete jungles.
Nature is what the real world is. Not the artificial world humans have built. The bliss, calm, serenity you’ll experience is priceless.
Go out there.
It’s one of the simplest advice, though, can improve the quality of your life incredibly.
