When possible, I also try to bring some of my hobbies into my work - or if nothing else, thinking about what it is I love about the hobby and bringing in that aspect into my work. I love music of all kinds and love to sing and play the piano. While I can't sing through my whole day, knowing that music helps me think creatively and also focus, when I know I need to do these things and have some quiet time, I'll put headphones on and play music softly to help me develop new ideas or plans.
Finally, I follow the mantra of work hard, play hard! Use your hobbies as a way to reward yourself and have something to look forward to, for example, on your weekends or days off. It helps me maintain focus all week long, when I know I'm going to reward myself with a fun activity on the weekend!
As you do a hobby it requires something from you: effort, concentration, problem solving, helping others, possibly leadership (are you leading the effort?), coordinating people or resources, meeting and working with new people to accomplish goal, etc. The key is to reflect on your own hobbies and determine which skills you had, you’ve gained, and/or are working on.
Be curious. It is hard to connect with people you can't find something in common with.
Build relationships. Be courageous and approach people to learn about them. Create a network
Develop advocates. Key leaders/workers that can help you on your path. It IS who you know...
Know your business. Always look for how your business continues to change. It IS also what you know...
Be human. Don't forget to be human. Volunteerism in the community can help shape gratitude and perspective.
