Missions must be entrepreneurial. Typically this means that you have been inspired with an innovative solution and that you have lead the charge to fill the need. You must be a leader or a co-leader, a founder or co-founder, of a solution. You must be more creative than volunteering for another Mission or existing charity.
Missions must philanthropic. They must benefit people or a community or society or the planet.
Fundraising alone does not constitute a Mission. The many popular and easy-to-use crowdfunding sites are a great way to fund a Mission but this effort alone is not adequately entrepreneurial. It is not necessary to raise money as part of a Mission.
