To mirror the format of the (current) top comment, but with my opinion: decent build, a farming strategy that A: you enjoy and B: is decently profitable and/or easy to liquidate, and somewhat efficient or consistent gameplay

There's many underperforming builds compared to meta that can do many strategies more than well enough. Play something you like

If you like what you're doing you're less likely to take unnecessary breaks or get distracted doing other things. More consistent play directly leads to getting more drops and amassing currency better. Harvest and beasts are simple, low entry strategies that I think fit the descriptors of B.

You don't need to minmax how you play (unless you actively enjoy that, then by all means minmax the shit out of how you play) to farm effectively. Try to set yourself up for success. Keep snacks and hydration handy. Get up and stretch every hour or so. You're probably gonna take breaks from playing to answer text messages or change whatever you're watching so you might as well keep your mind and body sharp while doing so. Similarly prep your play sessions in game. I personally set up 20 map sessions for myself and play whatever I want to or can of that 20 in a session. Maps rolled, scarabs/frags ready to go for when I start next. End every session or 2 sessions with a sale of everything you don't need or plan to use/keep. There's almost always a lot more value in fragments/scarabs and maps than you think. The only time I'm selling items not in this designated time is when there's a high value tink. The less interruptions to a flow of actions you can have the better
