There are bright people: they have a certain elusive charisma, pleasant manners and a broad outlook, invariably attracting others to themselves. If you are not naturally endowed with such qualities, but also would like to interest people, this can be achieved by working on yourself.
Wide outlook
You can be an excellent specialist and be well versed in the field with which you work and attend continuing education courses, however, a discussion of accounting or the specifics of writing programs in one of the programming languages is unlikely to help you start a casual conversation with a stranger. Write a list of topics that interest you and that would help you start a conversation with a stranger. For example, it can be new cinema, modern Russian literature, city news, fashion trends. Deepen your knowledge on these topics, read magazines and watch programs dedicated to them. Such conversations will be of interest to a wide circle of listeners and, having learned to confidently and excitingly discuss the latest trends in the world of perfumery or contemporary poets, you will win the audience.
Appearance
A well-known proverb claims that people first value each other by their clothes. Of course, then they pay attention to what you are talking about, the way you behave, but the first impression consists of the appearance. Therefore, you should try to look decent. Interest is caused by people who have their own style, but at the same time looking appropriate. If you are afraid of making mistakes and are afraid to experiment, get an original accessory or jewelry that will catch your eye - an elaborate brooch, a painted neckerchief, and an old pendant. Such a detail will attract the views of others.
Interesting hobby
Get yourself a hobby. It is better to give preference to something non-trivial: not collecting stamps or modern dances, but, for example, embroidering traditional patterns of Indian tribes, mountain climbing or Japanese dance with fans. Such a hobby will add a bit of unusualness to your acquaintances and will cause interest in you. You may not find anyone to share such an unusual hobby with you, but a bit of uniqueness will add value to you in the eyes of others.
