According to psychology, first impressions are very, very important. They get lodged in our brain and make a permanent impact that fact cannot change. Take that information and apply it to your professional life. Here are some tips for you to make a great first impression in your professional life.

Be on time. Punctuality is king. Being late or being too early can hurt a first impression.

Be comfortable in your skin. Confidence is attractive. Arrogance, however, can be problematic for some and can cause a poor first impression.

Smile. No matter how your day has gone up to that moment, think of something that makes you genuinely happy and let that thought translate to your face. Sincerity counts with your facial expressions. Fake smiles can set some people on edge and make them suspicious of intent or truthfulness.

Dress appropriately. If you’re not sure how to dress, research. Ask others who have been in that setting. Stop by where you will be interviewing, or meeting the person/people and see how they are dressing. Then dress one step above. Make sure you are looking your best with hair and makeup, not overly done up.

When you can arrive in style, do it. Hiring a car service or limo to drop you off at a big event will help that first impression especially in Chicago.

Be positive. Your attitude no matter the situation will reflect on your countenance. It also affects those around you. Be sure you are in a positive frame of mind. If you’re having trouble, smile or laugh in your car before entering the building. It will help fake your brain into being happy.
