One comment that I would offer up by way of expectation management is that mining and industry, though tightly related, are very different from both an activity and skill perspective. Particularly when getting started, I would heartily suggest reading that article that @Do_Little posted.
My comments here are assuming Omega status.
Mining, by far, is the easiest one to have some level of success with since it is relatively accessible and easy to get into a barge fairly quickly. Once you get that down, you have the choice of how far down the rabbit hole you are going to go:
- Mine then sell the ore
- Mine and refine the ore and sell the minerals
- Mine the ore, refine the minerals, and use them in production
Obviously, each of those requires more skills and standings to optimize the results and profit. Finding a good corp with fleets, hauling, boosting, and refining facilities can help a lot here- but if you get into refining, there is quite a lot to train. Happily, there is overlap with some mining skills (such as the use of crystals), but it is a much longer path to go down.
Industry, specifically manufacturing, is quite a different beast and is deceptively complex depending on how far you go. One key thing to remember is that, for the most part, T1 mods and ships are not going to make much, if any, profit in a lot of cases. The money is to be found in T2 modules, but the complexity ramps up substantially for a number of reasons.
First, you need a lot more materials to build these items. In addition to basic minerals you will also need materials that come from Planetary Interaction (PI) and commodities made up of moon materials. It is extremely difficult for a single player to manage all of that solo, so having a good network of suppliers or a corp (with the right resources) to assist is almost required. Second, the skill tree also becomes a lot more complex as you will also need Science skills to research and invent T2 BPCs. More info can be found here:
Now, let me pause to say that I am not posting all of this to be discouraging. I just want to kick over all the rocks so you can see how deep this can go and how involved it can be. Better to know now than after sinking a bunch of time into training only to be hit with a whole other skill tree to train that you weren’t expecting
Here’s my advice for getting started and seeing if this is for you.
Train into a mining barge. It will only take a few days at most depending on what you have already trained. Purchase some BPOs for some things that you personally use a lot of- ammo, drones, that kind of thing. This will be less about making money and more about saving money and hassle buying and moving those items for personal use. Next, find a contract for a BPC of a ship that you want to build to get a feel for building something bigger. Train the skills to build those items and have a go at it. While you are doing this, look at other BPs and skill trees to get a sense of both the process and the requirements and see if this is something you want to do. If it is, take the next steps.
Keep training the industry and mining skills and take a stab at getting into PI. Even if you decide that industry isn’t for you, PI is a good source of passive income- particularly in NS/LS space. As a Caldari, start out making some Rocket Fuel and set it aside. Then, take a stab at inventing a T2 missile BPO and building a few with your items, minerals, and PI commodities.
If you are still having fun at that point, congrats- you’ll be a rocking industrialist! If you’re not, no worries- you have some stuff to sell and can reassess what you want to do.
Hope that helps!
