To restore knowledge from silence you must need to increase hearing capacity, Ears can only detect sound between 20 Hz-20Khz. So much going around beyond that frequency & neither we can hear, nor we are ever tried, even many people can and they have an access onto those objects.
Doing something alone means you are capable of doing it.Whether it's small or big task.....Do by yourself...It will reflect your intensity towards your WORK.....
