Don’t focus of creating a network of people as a different task and a separate activity just for the purpose of having people around you.
Networking must happen in parallel to the core job that you are doing.
Real bonding between different people happens as a result of the kind of valuable work one is offerings and the value one to could offer to the other person.
A long lasting network must have common core values and work together for a common objective.
A network of people without a common sense of purpose and mindsets do not have strong relationships. This kind of bonding would be superficial and temporary. Having a network of people without real meaning would be transactional and need basis. For example: In the corporate world many people talk to others to realize their business/career needs. May be to get a business deal or to get that promotion etc.
