Employers may specify that you need a degree, but more and more, they are equally looking for people who have the subtler skills which will dictate that they approach a role in an effective way. So, whatever activity that you engage in, it’s important to tease out which skills you are developing.
It may be that you are purely doing something for pleasure, but if you think about it more reflectively, you might conclude that you have gained some useful skills as well and, when writing applications or attending interviews, being able to use these examples can be invaluable.
Some soft skills can be taught and you may have some naturally on account of your personality. However, it might be that you need to work on others perhaps by finding opportunities or choosing activities specifically. So, for example, when working in groups, you might choose to lead when normally you would let someone else. Or, you might apply for internships with certain companies to boost your commercial acumen.
