I think your attitude is awesome! Never stop learning for the rest of your life. My grandfather is a surgeon and still travels for conferences and learns new things, and the man is 80 years old! I always tell myself that if he can still learn something new so can I. It keeps your mind sharp and enhances your critical thinking and patient care. Do not lose this fervor for learning!
I think the "why bother" reaction is from people who have gotten set in their way, or know what works for them and don't care to enhance their practice. This is the wrong attitude to have, especially for patient care. If we are to deliver the best care to the people we care for, we should be up to date on best practices. This however, is often challenging to implement, given this pushback.
The other factor in why you might be getting pushback is your experience. While you have 7 years as an ED tech (I am assuming), and 1 year as a nurse, your nursing experience might be a credibility factor. I know this can be frustrating to hear, and while it may or may not be a true factor in your knowledge, it may be a perceived factor amongst your peers. A senior nurse being told "the latest and greatest" in medicine from someone with one year experience in nursing may not be taken well.
I think the best thing to do would be to continue to grow your knowledge base and be a resource for people when something comes up! Keep your chin up and your mind open to learning new things.
