How skilled do you think you are at your job? How skilled are you at your hobbies? Is your skill level between your work activities and your hobbies connected?
I believe if you find ways to connect the different skills you have, you will be more effective in all areas. In looking at different aspects of your skills, you can find useful perspectives that you already use, but in different areas of your life.
Typically, only soft skills are described as transferable skills. Abilities like public speaking, leadership, time management, and interpersonal skills. I allow the definition to be quite a bit wider than that. I include understanding different organizational systems, competence with specific technical software, and understanding design principles as transferable skills, as well as most other technical skills.
With each new skill that is added to your toolkit, you get a new mindset that can be drawn on. Whenever you are actively using a skill, you may notice that you start to see what you do in a different way. You shift into a different mindset to better use your skill.
