If he could, we all can.

I had the privilege of meeting someone really senior and very experienced today at work and I asked him something. It was something very routine and mundane. He very humbly requested me to do it for him and said he would learn that from me some day. 

Profound humility.

Even today I tend to rethink before asking a question because I think its silly and assume I would be judged. 

If someone at that level could so humbly accept that he needs help with something, then I think we all can. No one knows it all, and there is no shame to it. 

So ask and you shall receive!
