A friend is visiting Costa Rica. One always expects to see a lot but we saw 4 Quetzal birds in a single tree and 3 sloths and over 20 tucans on a single short drive.
He definitely realises how lucky he is but for many, they visit and go away not having seen any of these things.
We should always remember that our perceptions are based on our experience and our personal experience of a the same situations or events as other people may not lead to the same perceptions. Listen accordingly!
