this 'problem' seems to be endemic with many people, but at the end of the day, you need to stop making excuses and go out and take photos. That simple.
Yes, this is easier for me to say because I am fortunate enough that because photography is my job, I have equipment that does not limit me (far from - and yet my equipment is 'inferior' to a fair amount of what you shoot with), but even if your equipment or access or life DOES limit you - for example, you only have a kit lens and want to go and take photos of small birds - then work around that limitation. Superclamp your camera to a branch next to the bird feeder and fire it remotely, whatever... or go and shoot something different entirely. Not a bad thing - but if you have full control of the photo, it exercises a lot more parts of your brain, namely actual creativity, rather than just technical skills in getting the shutter speed right.
if your pictures suck, it's not because of your equipment, it's not because you don't have some lens or magic doodah, it's because of the soggy matter in the 6" behind the camera, and there is ONE way to improve that, and that is to go out and take photos. Or better, much better, /make/ photos. Sounds like a flickr cliché, but it's a real difference - and almost ALL of the photography on this site, you have no control of the photo other than what you're doing with the camera.
so stop making excuses 'oh wow my photos would be so much better if I went out and bought the latest thing', actually go out and take the best photos that you can with the equipment that you have.
