That's solid advice, but I'd push back slightly on one thing: the Thieves Guild radiant jobs angle is real, but they're not where pickpocketing actually shines for early funding on Switch.
The real move is pickpocketing in places where you're already stuck waiting around or doing other stuff. Like, if you're doing the College of Winterhold questline, you're literally living in that tower with the same NPCs every day. Steal their robes, their rings, their potions while you're there anyway. Same with the Companions hall or the Temple in Whiterun. You're going to be there multiple times regardless, so the time investment is basically zero. That's where it stops feeling like a chore and actually adds up.
Also, ngl, the perk that lets you pickpocket equipped items without them noticing is genuinely game-changing once you get it. Suddenly you can walk around Markarth and just... take the iron dagger off a guard's hip, take a mage's robes while they're standing there. It feels ridiculous and it's way more profitable than sneaking into a shop to grab a potion bottle. By that point (level 20-ish Pickpocket) you're stealing actual gear, not vendor trash.
But yeah, if you're actively trying to farm gold early on, just loot bodies. Pickpocketing is more of a "this is how my character moves through the world" thing than a strategy. Don't make it a side job.
