Not every project you work on has to inflate your bank account or your professional status.
Sometimes you decide to work on projects because of who benefits from the finished project, like building a Habitat For Humanity home or contributing time and energy to other worthwhile charity projects.
You might choose to work on a project because of the knowledge and experience you’ll pick-up as you work on the assignment.
Another reason to work on a project are the people you’ll get to associated with as part of the project tasks. It might be a networking opportunity to connect with potential business prospects, or it might be the chance to come in contact with local or national celebrities.
Finally, you may simply choose to work on a project because you think it would be fun, or because you think the project sounds interesting. There are worse reasons to work on a project than “fun and interesting”.
