In any project, any job, and for that matter in life, we need to surround ourselves with a consortium of people who support us. Seek out those who can help you, challenge you, and support you. They will encourage you when you need it, and they will challenge you in your own growth.
As you collect these invaluable relationships throughout your career, stay in touch, even when they move on to another company. Don’t forget that you should also find ways to support them.
You can’t dig a well when you’re thirsty. Build and protect a strong consortium over the course of your career and nurture it. Don’t forget that you can “vote people off your island” who prove to be inconsistent with who you are and how you live.
