If I'd be 1 month old then yes.

Profit /m3:

1.0 Security
- Veldspar (120.09 ISK/m3)
- Scordite (108.08 ISK/m3)

0.9 - 0.8 Security
+ (Gallente and Minmatar)
- Plagioclase 138.01 ISK/m3

+ (Amarr and Caldari)
- Pyroxeres (148.61 ISK/m3)

0.7 - 0.5 Security
+ (Amarr)
- Kernite (134.00 ISK/m3)

+ (Caldari)
- Plagioclase (138.01 ISK/m3)

+ (Gallente and Minmatar)
- Omber (72.36 ISK/m3)

Systems with 1.0 or 0.9 security have no NPC pirates.


But you can also try Mining Mission. They don't give you ORE but instead LPs and ISK. You could run those with your frend.
+ 3x more ISK/h than mining in High Sec
+ Getting better standings with Faction and Corp
+ No danger of Can flipers

- The ORE you mine is used for the Agent (You can't do anything with it)

Miner/hauler is a good start.

You'll both want refining skills trained, if possible. You should both have research and manufacturing as well, because slots become the limiting factor after a while.

Mission running/salvage: Mining out missions is a good way to get non-local ores. Plus, they're safer in terms of can-flippers; your regular jerk/griefer/goon PROBABLY won't bother to scan missioners down with combat probes just to pick on miners. They'll just stick to the easy targets in the belts instead.
Plus, missions mean bounties and ISK, and salvage/loot can get you materials for production, especially rigs. And a good supply of meta-level items to either be sold, scrapped, or thrown into T2 invention.
And STANDINGS! Standings are super-duper important if you don't want to risk having your PoS popped by a passing supercap fleet in lowsec. With standings, you can anchor it in highsec, where the worst thing around is a fleet of battleships with very patient pilots.

Train ice mining and PI as well, to lower the ISK costs of the PoS you'll invariably need to run.

Alts. More characters mean more slots!

EXCEL. Spreadsheets are key to EVE. Absolutely key. Running the numbers can mean the difference between loss and profit on an item. Even going with just raw input to output, it's useful.
And you'll even know when you hit REAL profit, after paying off the expensive mining ships, BPOs, haulers, and PoS modules.

Market skills. You'll need to milk every last ISK of profit margin.

PI is an easy way to get started, in addition to mining, and has the advantage of making you ISK while you do other things. In about a week, you can train you and your two alts with enough skills to run a nicely profitable PI operation. Profitable PI goods are things like POS fuel ingredients, which are very liquid meaning you'll start seeing decent cash flow very quickly. You'll get the best ISK flow if you keep everything in one system and keep all your toons nearby. Part of the training time includes training enough skills to be able to use a decent hauler. Eve Uni has a great page on this:

With an investment of about 30 minutes a day (to move your PI ingredients around), you can crank out profitable PI goods rather quickly. When that gets boring, you can back off to just a few times a week or not at all. I still do PI about twice a week, but my first billion was largely due to daily PI and a few lucky drops from rats.

EveUni has a pretty decent page on PI here:

I also did the mining thing when I first started but note that it takes a good month to get your skills where they need to be. Namely: you want to be mining with hulks.

These days, I don't mine that frequently. I get most of my materials from security missions and put out buy orders if I'm saving up for something. Missions can also be quite profitable but you'll eventually want to train up scrapmetal processing which will burn another month of your life away.

One final note, don't overlook rare ores in missions or from exploration. I've never found anything too exotic but you DO find ores not native to your particular neighborhood of high-sec. You can also occasionally find rarer ores by scanning them down. If you DO find some rare ore in a mission, you can farm it by mining and then not completing the mission. Unless things have changed, the mission will reset during downtime and you can mine all over again. You can keep doing this until the expiry time of the mission. All you'll lose is the time completion bonus.
