How do I develop a strong presence and personality?

Smile anytime you talk to people. Speak clearly and make your message clear.

Have an interest in other people. Be very optimistic and have some positive attitude.

Wear clean shoes. Don’t just wear anything but dress with sense! Appearance matters a lot, the way you make yourself presentable is how people are going to treat you.

Be very knowledgeable, try as much as you can to have deep knowledge on different topics.

Avoid cognitive bias and generalization, try engaging your common sense in some mental effort.

Boost your confidence by always learning new stuff every day. If you can afford it, travel as much as you can.

Walk like a boss. Walk straight and look at strangers, they should be the one to take their eyes away off you. Avoid moving your eyes rapidly.
