Your first name of Knocker makes you quick-minded, versatile, and very expressive. You have the ability to create a favourable first impression, and so you could do well in the fields of sales promotion or entertainment. Talking comes easily to you, but guard against your inclination to talk too much, especially if you are over-stressed. It spoils patience and weakens your stand in matters of principle. You could, at times, be too easily influenced against your better judgment and be led into activities that put you at risk. You make the effort to communicate with others because you place importance on having people like you. Your name creates two conflicting natures. This name has given you an interest in people and a desire for new experiences. These upsets drain your vitality and make you tire more readily. You could suffer bitter experiences through attracting wrong types of association and can be drawn into circumstances involving you in unwise situations.
