Social skills is all about being. Being yourself. Listening to the other and staying in your own body instead of pinging of the other. Having fun, seeing the world as a light place. I socialize daily and with everybody I encouter. I just love people and I love to talk with everybody. I find them interesting and I always want to learn about somebody. Their hobbys, values etc
If you are not good at socializing its probably because you are more in your own head then being engaged with the person you are interacting with. One thing you might try is just to shut up and too listen to the other. Most people rather talk about themselves then listening to the other. Make use of that fact.
