one's own wishful thinking

attain the highest level in one step

not to be the least bit negligent

Say all you know and say it without reserve

be in the forefront

lit. the heart of a sheep in the skin of a tiger (idiom); braggart; fig. impressive in appearance but lacking in substance

cling to one's view(stick to what one says)

have eyes but fail to see

He who excuses himself accuses himself

be a beast in human form

echo each other

make self-criticism as one who draws a fire against oneself

as crooked as a crokscrew

take up one's brush and dash off

know no fear

play the same tune on different instruments

pit one against ten

speak glibly

in the course of frequent contact(in the course of time)

water rushes down and covers hundreds of miles of land
