To become a good leader as a young manager, you ought to be a good listener & a willing learner. An attempt to learn from the experience of your subordinates will make you earn their respect. How much respect you exhibit towards your own boss will be another factor that will increase your acceptability as a leader.
A 'Leader' is essentially an individual whom all others like to willingly follow. This requires a lot of sacrifice, more so of one's ego, sometimes to the extent that you even forget (while working with your team) that you are a manager. Let others feel that you are a shade superior to them in your behavior & mannerism, and never do things to singularly benefit yourself. A leader is always firm yet polite, always approachable, always helpful, always smiling and who never tells his team members, "I have no time". A true leader is professionally knowledgeable, intellectually sharp, socially amenable and the one who searches for only good in others. You can't criticize others, yet dream of leading them successfully.
Savvio, true leadership is very little of what you read in the books. My own experience makes me quote:
"Heights by great men reached and kept,
were not attained by sudden flight;
They, while their companions slept,
were toiling upwards in the night"
