Knowledge is power.
There are many ways to get the attention of others. Our way of conducting and how we organise ourselves will have a big say in getting the attention of others.
Thoughts exchanged is knowledge gained.
So, it is not all about gaining attention, it is how you manage others to pay attention to you that should matter. People must look at you and come up to you and most importantly must not feel discouraged once they start talking to you. It is not easy to maintain the initial attention that one may gain with his looks or appearance. For that, you need to be well-behaved and must know yourself well.
One must not be artificial, either in looks or in behaviour. Again one must not be overly conscious. You tend to be artificial in whatever you do when you are conscious that you are being watched. Be your natural self. Though it is not wrong to seek the attention of others, it would be better if we do not do or say something extra to gain attention. That would be the purest form and it can be truly satisfying.
