This is another way to remain visible to your network and stay current regarding trends in your field. For trade organizations, offer to write blog posts or help with activities that can be done remotely. There are also many global organizations that offer volunteering opportunities. The Gates Foundation provides a great resource for volunteering in the US and abroad. Chose one that fits with your current field and/or an area where you want to gain more experience. This is where a little bit of planning goes a long way.
