There are a lot of thinking skills, many ignore them and comment as if they consider communication skills is the most important one, leaving aside other critical skills!
It's always pretty difficult to separate skills out, and also this depends to an extent on the organisation/role. I think though that it is important to get on with others, which involves communication but also respect and self-control. Secondly it is important to be a good problem solver and to be able to adapt to new circumstances. This helps you to use past experience to tackle new problems, and allows you to be an asset to the team (a closely-related point is being creative in your approach).
Communicating skill is certainly an essential one which is connected with the attitudinal domain. Communication means the ways one deals with others by way of words we use. Our ears must be attentive, our words must be tender, and with clarity. a person interested in developing life skills will then become eager to gain other necessary skills as well.
I agree with all of you. I would also add the skills related to the area of critical thinking, decision making, the search and appropriate use of knowledge and specific skill sets to solve problems / adapt to the social or work context and resource management (including personal capacity).

One that has not been discussed so much is workrate/productivity. In an academic context, some are highly productive, and others do not produce so much. The ability to organise yourself, meet deadlines, collaborate well, and write a lot – these things will help you advance.
