LEADERSHIP
Knowledge is not a fixed quantity that shrinks when it gets shared. Somebody secure in their own ability can teach you everything they know without feeling smaller, because their worth never rested on being the only one who could do it. The opposite behaviour, hoarding small techniques, tends to signal insecurity rather than value. Being outgrown is the point of teaching rather than the risk of it.
Notice which people around you share what they know and which guard it. Learn from the first group and do not take the second personally. Then pass something on yourself, especially a trick you feel protective of.
Have you held back teaching someone because they might surpass you?
