Reasons for people to come to work for you:
I need a job to pay my rent, do my hobbies, and do other things.
Here is where I am going. I see you are also going there, and I would like to join you.
I believe what you believe and want to join you in making the change and serving the people.
It helps to hire people who need a job, but the people who believe what you believe make a better team to create the change you seek.
