Enter networking situations planning on being helpful to your associates. The benefits to you will follow. Spend quality time with each person. Find out what they need, and let them know how they can help you. Attend a few diverse networking groups consistently.
Quality counts over quantity.
If you are too aggressive, you will be branded a hustler. Maintain good eye contact, and work on your non-verbal communication skills. Always carry business cards. Write the circumstances of the meeting on the cards you receive. Networking just develops leads.
