Prioritize

If you have too many stakeholders, it would help to prioritize them based on how justifiable your investment in that stakeholder would be, how powerful the stakeholder is, etc.; for example, you can sort your list of stakeholders so that the higher-priority ones are at the top.

This prioritization helps you direct your efforts, and, for example, if it’s a difficult time in your project and you can’t care for the stakeholders as much as you expected, you might only do it for the highest-priority ones and accept the risk of leaving the rest on their own.

Don’t forget that priorities can change as you progress, though.
