I switched from Photoshop to Sketch ..and now spend less time doing more work. Reason being that, as already mentioned, Photoshop was never really designed to be used for UI design whereas Sketch was. Yes Sketch is still a bit wobbly in places, and yes Photoshop still dominates at image manipulation. I think it really comes down to choosing the right tool for the job, and having both of these tools to work with has been phenomenal. Highly recommend :)

Hey Tobias, I've been following your work for a while now, really love what you've been doing. What would be one piece of advice that you would tell your past self about when you were starting out?
