It is Easy
I quite often hear people tell others how easy something is. This is sometimes done by people who have actually perform the job while explaining it to others, but more often than not it is by someone in management telling “workers” how easy something is. In either case, don’t.
It belittles others.
Be grateful you find it easy, but many others don’t posses the skills nor talents you do. If it were so easy, then you would have done it in the time it took for you to explain it. When giving direction and implying it is easy, then others will be hesitant to give more appropriate estimates and voice concerns. This turns you into a boss instead of a leader that you should be.
Also don’t speak as though it is extremely hard. Use your words and describe it accurately or let them define how easy/hard it will be. Ask for their input, listen to them.
