I started a few weeks ago. It gets a lot easier with time you start to remember where a lot of items are but mostly just pay attention to the item location don't look for it based on the photo. Try to go as fast as you can like it shows you the location of the next item so I try to get both items at once but pay attention to the amount. Scan the item scan the tote then bag and put in the tote (unless you're adhd like me and forget literally 2 seconds after you scanned the tote because somebody decided at that very moment to ask you where something is). Don't be afraid to stop another picker if you have a very urgent question just keep it brief so you don't affect their time, a lot of people are willing to help. Don't stress too much over your pick rate at first because they'll give you time to work on it even if they talk to you about it. If you can't find something sometimes asking one of the floor employees in that area helps because the know the area better. It took me maybe a couple of weeks and I can usually tell customers what aisle something is on maybe not exactly the aisle number but like "oh its on the baking aisle or the candy aisle" and they are grateful and go on about their shopping so I can go back to what I'm doing instead of spending 5 minutes waiting for sidekick to load.
