The single greatest thing you can do to be more clear, calm and collected is to not take anything seriously. If you don't take anything seriously you won’t take anything personally.
If you don’t take anything personally you won’t get stuck in drama and blame and resentment and anger and all of that.
If you don’t get stuck in drama you can see clearly, you can see the big picture, you’ll have options.
If you have options you can do stuff easier and have more fun doing it. It’ll become an endless upward spirally loop of greater and greater joy.
Let me reassure you: The path to being the best version of yourself is through increasing amounts of joy. The enlightened beings I have met all laugh their arses off, constantly.
And here is the thing - a happy, joyful destination cannot be gained through a serious path. It is impossible.
This is good news. Awesome news actually. and its easy.
As my meditation teacher says, don’t worry about forever, just take nothing seriously today. Start small, but start now. If you like it, do it tomorrow. You may just find you keep doing it.
Find ways to laugh at everything, including yourself. Nothing need to be serious. Nothing benefits from seriousness. Even the most serious discussions benefit from levity.
Hang out with the happy people. Help others laugh at themselves, help them lighten their load. Don’t take anything seriously. Life is too short not to.
