Error During If and And-or-not Statements

For my assignment I needed to create a club and have requirements that the user has to answer via three inputs, and I also need to include an if statement and an and-or-not statement. I sorted everything out and it was working swimmingly until the and-or-not statement. I am learning via an online class, and I just briefly learned the and-or-not statements. They showed examples using numbers and two options, but I have way more and they're word options. I am not sure if I am coding it properly, because even if the person enters false values, it still outputs as if it were a true value. Any advice to fix the issue?

    print("")
    print("Thank you for filling out our quick admission form! :)")
    print("")

    print("Your answers to our form:")
    print("Age: " + str(age))
    print("Profession: " + str(job))

        if( age >= 18):
            print("Welcome, you meet the requirements to join the club!")
    else:
        print("Unfortunately, you do not meet all of the requirements to be in the Programmers Only Club :(")
