Learning Photoshop has been a life-long process for me. I’ve been using it for about 7 years. And I feel like I’m constantly learning new things with it. It’s such a playground that the most important thing when you open it is that you have a destination in mind. Sketching before touching a mouse is paramount. It’s like a secret weapon Photoshop competitors. I encourage people to use it as much as possible. But I also encourage cross-pollination. People like myself love teaching it even more than using it. Ask designers to teach you something if you want to learn!
