“The worst they can say is no.”
We have all heard this, right? Well, it can be a very useful tool. If you see a professional/expert out there in the world right now who you want to learn from, there’s no harm in asking for advice or help. The worst possible situation is that they don’t reply or they say no. You never know; they may be eager to share their knowledge, or they may be looking for someone to take on their mantle in the future. You may also have the skills, time, and ability to do a task they have been meaning to do, but have put off because of their busy schedule. Who knows! You certainly wont until you ask.
Being polite, professional, and eager is sometimes enough for an expert to make time for you. They certainly won’t be working with the person who never asks.
