2. How do you approach a professional(someone senior to you) and not get ignored?
3. Any networking tips you've gained through experience..
Networking is not marketing and you should not approach it like marketing. It's about creating a network of reciprocal, trust-based relationships. The main currency in the network is trust, and people stake their reputation every time they connect people with each other.
In-network transactions are frictionless because the usual diligence is not necessary. You can use your network to get insider advice, trustworthy recommendations, profitable contracts and mutually beneficial deals, yet never write a single contract or issue a single invoice. It's all based on trust and the assumption of goodwill.
