You have to become comfortable with being uncomfortable. I was scared of randomly ringing people up or asking for an introduction. You might need to be cheeky, and pushy, and not afraid to ask, and that was a real hurdle I had to overcome as well in the early stages, having that confidence when no one knows who you are. But honestly, when you ask, 9 times out of 10 people are really flattered that you want to ask them and that you value their opinion. So, I think the advice is just to go for it and get stuck in.
