Over the years I've posted grant opportunities and I can count on one hand the number of people who have applied (that I know of). That's sad, because although it is a big chunk of work to put a grant application together, once you have all the info you can use it again and again and dramatically cut down on your prep time. The people I've helped with their grant applications have sometimes been successful, sometimes not (which is typical), and I urge them to reapply next time although they rarely do. Again, sad, because there is a lot of funding out there if you are persistent in pursuing those that are a good match for you.
This came across my desk and it's a goodie: The John Simon Guggenheim Memorial Foundation provides fellowships (in cash) for advanced ("midcareer") professionals in all fields including the natural sciences, social sciences, humanities, and creative arts (except the performing arts). Last year they helped 181 scholars, artists, and scientists in the USA and Canada by funding for blocks of time so recipients can work with as much creative freedom as possible (six to twelve months) in any manner they choose that contributes to their work.
Unlike many other funding opportunities that are only for non-profit organizations, this one is only for individuals (writers, scholars, scientists, artists, playwrights, filmmakers, photographers, composers) who are often characterized as "midcareer" (they have a significant record of publication or a significant record of exhibition or performance of their work).
Here's my biggest secret for success when applying for grants: Read the directions and follow them to the letter. Seriously. Doing that will get you further, faster, than anything else I can recommend.
Good luck! Let me know if you need help.
