Flight school and your instructor
shop around for both the person/school you may go to first may be the best person?school but maybe not.
you must be 16yrs of age to solo and 17 for your license
you will need to get a 3rd class medical www.faa.gov/pilots/amelocator to find the Dr near you that is certified to give this exam
FAA regulations require 40 hours of flight (national average is 80-90 hrs)
Time and support
It is my opinion that this is just as important as the above mentioned items. Learning to fly is a big undertaking especially if you work and have a family there is often little time for studying and dedicating yourself to being the best pilot that youshould and have to be. There are so many ways to get this support first starting with friends and family get them involved maybe your spouse or a friend has always wanted to learn to fly or maybe just help you study. Almost every airport has a pilot's group you could join and befriend local pilots who love to share their experience with you. Even on a national level there are groups that provide support and information I belong to AOPA www.aopa.org and highly recommend it. I also belong to the 99s www.ninetynines.org which is a women's pilot organization. Obviously with the internet there is no limit to the information you can find. It can be overwhelming if you have any questions I will try to answer them
