When you go outside, take time to let all of it sink in.
If you're in the city, take time to watch the people. The cars. The buildings. Look at the behavior and architecture. Listen to the city noises. Breathe in the city scent. It's all beautiful in its own way. Not crowded so much as filled.
If you're more around nature, look at all the plants. The colors. The animals. The landscapes. Look at all the shifting shades and moving shapes. Listen to the natural music nature makes. Breathe in the fresh scent of dirt, animals, trees. It's all beautiful in its own way. Not so much lonely as quiet.
