Do you like to smile? Sometimes I find myself do not smile a lot and this gives an impression to others that I am not friendly. There are many types of smile, some are fake and some are real, and it's pretty depended on the situation why you smile, if you in an embarrassed situation, you will have to fake a smile, just to make the situation better.  

Recently, I've read a book, and it says that to smile effectively, you will have to pause for a second before you smile to the person, in this way, the person will only know that the smile is for him/her and not that you smile to everyone. These are a good practice, and I have tried them and to my surprise, it really works. However, you may not want to overdo it, and I have been practicing them with my female friends and one of them tell me, why do you smile like that, you smile like a pervert with saliva dripping from your mouth, that's aweful. Okay! Probably, I was just trying with different combination, and maybe that's not a good one. I'm trying hard to fine tune my smile, and I am wondering why do I need to practice how to smile, since monkeys know how to smile.  

Perhaps, smiling is just a courtesy way to respect other and yourself, and it gives you a big success in relationships. If your job is to deal with people, you may get a way ahead of others if you know how to smile effectively.   Till then, enjoy smiling..
