Editing with Adobe Lightroom is just as much a skill as taking a great photo but once you get the hang of it, it becomes extremely fun and satisfying. Everything you want to know about it can be found for free on Youtube. Tricks, tips, styles, the only thing you will not find is your own style. That takes time and a vision which only you have of what you want your work to look like.
If you do not already have Lightroom, you can find it here on Amazon in either a stand alone program or by a subscription to Adobe’s “Creative Cloud”.
