Build a Network of Support
It is important to surround youself with people who support you, challenge you to do your best work, and to lift you up when needed. Finding groups, both on and off line can be very helpful. Just knowing that others around the world are facing the same issues and can help you manage your emotions and keep going is so critical.
Over time, you will then be able to support others and provide advice based on your own experiences, which can be a powerful motivational tool. Which leads me to my last point.
