How can I be both soft and humble, and authoritative at the same time?
You want to do it? You can do it!
You don't have to be aggressive in order to be strong, and you don't have to be wiggly-wiggly or weak in order to be soft.
We think they are opposite qualities and we can only have one of them; no! I would say, you can have both. You have be sensible and sensitive.
Often people who are sensitive are not sensible, and those who are very sensible are not sensitive. But you have the great ability of combining both, sensibility and sensitivity. That is the skill and meditation is the answer. Meditate!
