In terms of sensual indulgence...
I take pleasure in sitting out on my driveway staring up at the night sky while listening to peaceful ballads. Always works for me. Especially if you have your favorite mug with a beverage of any kind.
I also take walks with no set path in mind as long as I have a general idea of where my home is. Headphones definitely a must. Lana Del Rey is my go-to in these situations.
I write whatever comes to my mind in my journal while I'm sitting in a cafe or coffee shop of any kind, namely around noon.
I listen to instrumentals of unknown artists depending on my mood.

Hot chocolate and lemonade are wonderful at keeping me attuned in the present environment. Dunno why, it's these two that really make me feel peaceful. <3

And the best one? Going to Fisherman's Wharf in Monterey at 3 am and walking alongside the docks, listening to the sounds of the waves in quiet solitude while playing 'Never An Absolution' composed by James Horner. Especially when you go down by the water and letting that cold salty water take you away into a world of your own.That beats every pleasure in this world for me. That is a sense of belonging. <3

This is how I indulge.
