I wanted to redesign our app (which was previously done in Photoshop), and so I just dove in and did it with Sketch. Instead of starting with tutorials first (which to me is a bit like putting the cart before the horse), I just started the project, and when I hit problems or didn't know how to do something, I looked up solutions.

This has it's positives and negatives: - Pro: You dive in and learn quickly on a real project without doing boring studying - Con: You can often miss out on best practices that might save you a lot of time

You ultimately have to decide what works best for you, but I'm a trial-by-fire type of person.

For me, the increase in my speed of designing interfaces by moving to Sketch was pretty wild. I was slower at first, but quickly gained momentum and familiarity. The file sizes are much smaller than PS, it uses way less memory, and it's very forgiving. There are a ton of actions that take a shorter amount of time to execute, and these stack so that the overall feel of working in Sketch is just way, way better.

There will probably end up being comments in here about just using Figma instead. I can't speak to that, but I honestly can't imagine most design shops switching tools again in such a short time. Everyone moving to Sketch actually took a long time (the perfect execution of the 'slowly, then suddenly' principle), with a lot of hesitation on a lot of teams (and there are still plenty of holdouts). Whole workflows and expertise were built around Photoshop, and it's not a small switch to jump tools. Now it's considered almost backwards to do interface work outside of Sketch. Predictions are for fools, but I don't see Figma being the tool of choice anytime soon, even though it has some compelling features.
