Soft skills are a bunch of skills which complement "hard skills". Technical knowledge of any subject is considered hard skill. Common sense knowledge of anything is soft skill. Soft skills are also called corporate skills. Soft skills can be more useful and practical (than?/to whom?). Effective communication skill can be the most sought after skill by employers. Though "soft skills" are highly useful yet they seem not taught in school (direct/indirect?).
Today we need more soft skills than our conventional bookish knowledge. Soft skills are the basic requirement of everybody. Here is a list of most common soft-skills:
Maintaining a calm and friendly composure is as important as to making a worthwhile impression on others
Starting a conversation by a greeting, complement, social gesture and a simple comment about societal - relative topic like the weather and work your way up to other topics
Respect for others 
Even though you are exposed to someone who you do not know well enough to give them respect it is necessary that you give them the respect they would expect irrespective to whether or not they deserve that. Sensitive and idealistic men are hard to impress if you don't restrain your political and religious views (or any other as a matter of fact) to your selves
