Blogging is not always meant for writers to use. But, it is also used to be expressive in creative ways. For example, photographers and artists blogging their work. Through their photographs and paintings, they express who they are and what they enjoy doing because it helps them relax. It gives them a fresh and peaceful mind while straying away from things that will distract and throw them off-balance.
Blogging is not just expressive because it represents what you enjoy doing in your free time, but it rather signifies who you are internally and the amount of strength you show. In other words, what strong skills you carry.
