Take a look at the sky. There may be clouds, or it may be bright blue and clear. IF there are clouds, then spend a few minutes looking at them. In books & films it’s always seemed a ‘romantic’ thing to do, although you can do it yourself and still have the same enjoyment. The shapes of the clouds are always changing; see what shapes you can find, maybe try to draw them. If there are no clouds, then enjoy the blue of the sky. Quite often there will be a colour gradient of blue, and it’s so beautiful. Get some watercolour paints and try to recreate the colours on paper. If it doesn’t work then that’s fine, and you’ve just spent some time not-being-bored, and if it works that’s great!
