Life is short. So you should try to squeeze in as much joy as possible. Big or little, every bit helps.
One of the greatest things I have ever done for myself was one of the smallest changes I ever made. I have a small obsession with lighting/lights. I also never use the interior lights in my car, like ever. So I bought blue replacement interior lights off amazon for a whopping.....ten dollars. Even came with hyper-white license plate lights and a blue trunk light.
Took me another whopping.....ten minutes to put them in. Now, every time it's dark out and I go to get in my car, I am greeted with a flood of blue light. "un flot de lumière bleue" (that's French bitch)
I might be dumb, and that might not stroke everyone's fancy, but it tickles me blue. Best ten dollars I ever spent.
