If your image is well-lit, in focus and doesn't have motion blur, you are probably just missing post-processing. Most pictures will look rather dull until they are touched-up to make them 'pop' - you can have a look at the before and after images from this Google AI research project[1] that processes landscape photos to make them more pleasing to the eye.
Playing around with brightness, contrast, saturation and color curves can greatly improve a photo.

Do you have tutorials that go into detail about how one can improve? I've spent the last decade using Lightroom but largely going by what feels right rather than being more technical and deliberate.
Most of the skills are transferable to other editors just by learning the different menu options.
A good starting point for unsharp mask:
1st pass: Amount 10; Radius 30; Threshold: 0 2nd pass: Amount 100; Radius 0.3; Threshold: 0
Adjust amount based on your judgement. Don't over-sharpen. Sharpening should be the last step after resizing. Obviously always sharpen with the image at 100% zoom. Don't let your DSLR sharpen the image. Shoot in RAW, but resist sharpening at your RAW tweaking stage - just do exposure tweaks at that point, then bring into Photoshop for sharpening and resizing.
Also play with polarizing filters on your lens; ND filters so you can open up aperture to exploit the sweet spot of your lens; reduce your exposure compensation in daylight (my DSLR is always set two stops under); use a lens hood; avoid too much cropping, instead get the framing and focal length right when shooting.
And like sangnoir said learn how to post-process. If you're taking pictures in RAW format you'll be amazed at how much you can transform a boring picture.
