>>823496Photoshop is a very diverse tool that you can do a lot of different stuff with. There isn't really a catch all way to start learning it. What I'd suggest is just trying to make stuff you want to make, and as soon as you don't know how to do what you want, look it up. Specific stuff, like "How do I remove a logo watermark" or "How to cut the background out of an image" or "How to create a seamless pattern", "how to remove blemishes from portraits", etc. Most people who are masters at Photoshop got good by learning stuff that was relevant to the things they were trying to accomplish. As you find solutions for your immediate questions/problems, you'll learn new techniques and tricks that you can apply in other situations.
If you try to learn it in a "textbook" way, you're just going to be overloaded with mostly useless information and you'll get bored before you ever have the chance to make anything. For starters, try importing images (CTRL+O for files on your harddrive, CTRL+V for images you've copied or drag and drop into Photoshop). Select a tool from the tool palette (by clicking on it from the tool palette or by pressing its hotkey) and fuck that image up. Play with it.
