Final answer:
It is NOT recommended to ignore preparing, be late, appear messy, convey a lack of confidence, or have a negative attitude when making a first impression. Proper body language and open communication are crucial.
Step-by-step explanation:
When trying to make a positive first impression, the following behaviors are recommended: being well-prepared, arriving early, presenting yourself with a neat appearance, conveying confidence, and exhibiting a positive attitude with enthusiasm. Therefore, the actions that are NOT recommended when attempting to make a good first impression, such as exhibiting a lack of preparation, arriving late, having a messy appearance, conveying a lack of confidence, and having a negative attitude or a lack of enthusiasm, should be avoided.
Maintaining proper body language is also crucial in making a positive impression. Sit up straight to demonstrate good posture, and use appropriate nonverbal cues like maintaining eye contact, but avoid staring. These actions help to project a confident and professional image. Additionally, keeping an open and proactive attitude with good communication skills could greatly contribute to a successful first interaction.
