I too have wildly different area of interest, level of interest, and approach to things than most people around me do. Soft skills helped me to connect anyways, for at least two reasons:
1. With them I can approach, and connect to the interest of others.
2. I can explain to people my interest, and make it more interesting to them as well.
Also, these are not for all time, all the time. The healthy thing is to vary the guardedness in different contexts. The flexibility in this is a skill in itself, and again, something that connects to, and can raise, emotional intelligence.
