If you're at home, send the family to a movie or dinner out so you have the whole place to yourself. If you're in a public place like a park or library, try to get the spot that's the most isolated and quiet.
Sometimes you can find the most perfect spot, to contemplate, to daydream.
Choose different locations.
Of course you can have more than one retreat. Mine include my backyard, where I like to sit under the big tree behind my house, my car, when I go for a drive with no particular destination listening to my music and singing along (not well, but I try), and of course any quiet spot I can find at the park, where I can be surrounded by nature.
