is this not the right way to make science?

I usually come with ideas, because of what I read and so on, like why not apply technique A to solve problem B? at the end I have found the following outcomes:

• Sometimes I manage to make a research paper, and it has gotten published


• In other occasions I just let my idea to sleep, and sadly found that somebody else has made a research paper in some other country


• Or it has occurred that I found that the beginning idea was not good and end it up just like a technical report for my own

I was surprised that once when I told to a Professor to apply this technique X to Y, he told me in harsh way "that is not how science is made"; I was thinking if that is like so or should only make research if one has a tenured position or a research group at hand?

am I in the wrong path for making research? or should I wait to be into a research group?
