Don’t accept charity, because you can’t trust that the other person will show up tomorrow. But if you know the collaboration aligns with the other parties' interests, then you're confident they will keep coming back. Therefore the key to worthwhile collaborations is to navigate the organizational and personal interests of others. Make a mental note of the organizational and personal interests of everyone you meet. Then create a vision that aligns with their interests. Now you know you’ve set the conditions for success.
