There are more than 100 skills one should possess to succeed in any or everything. I will pinpoint few who has sub-category which will fall in the 100+ skills:
1. Marketing skills - Marketing is not only related to selling product or services. When we talk about the individual, every individual is a product, so selling our self to convince other to buy our ideology or thoughts is very important. Ex. When we go for an interview, we try to impress the interviewer that is called marketing. So it is essential to know our strength and weaknesses, so we do well in the conversation. Same way if we have a business, we try to convince our clients to buy our product or services. Marketing will include all soft skills to be developed to place you on top.
2. Critical Thinking - It is the objective analysis of facts to form a judgement. The understanding of any situation should be rational, sceptical and unbiased. We all need to develop this skills.
3. Self Management - It is self-explanatory. We need strong organisational skills, effective productivity habits and a sense of discipline, nothing more.
4. Focus - Focus on your vision, focus to be happy, focus not to let others affect you, focus to see positives and opportunity in every failure we get, focus on having a broader vision, concentrate not to get distracted what is not in our control, and so on.
Points may go on. I work broadly on these.
