You want to select a person. There are many who are competent enough to fill up the post. Your mental states could be one of these:
We are desperately trying – Sweet chestnut
I only want the people I want – having a superlative feeling, so Water violet. The plant of the flower Water violet is inside the water. In the same the Water Violet person is within his shell. To come out of our shell, we need Water violet. You will attract the person/place of your choice.
Our search is not good enough – Oak (by taking it we would have tried differently)
We keep asking people– Cerato, to make assessment. He tends to go on ask questions with uncertainty in the mind. Therefore, he will always goes to the person who is not right.
