I want to create thumbnails, images, and stuff. But is there any way I can grasp all the things fast and save my time? Because I really don't get that much time. So, I know photoshop would be the best for me but also I want to learn it fast. Any kind of suggestions or something you wanna tell me?
Focus on the tools and features that are immediately useful to you, and ask lots of questions in this forum. I can think of another user who started a while back and was keen to learn as much as he could as fast as he could. He (I have to admit I am only assuming that user is male) as ked lots of really good questions, and still does to this day, and he seems to be a capable Photoshop user now.
