My skillet is that I'm familiar with general codes and ways to make money from it. What I enjoy about it is it takes me out of reality and puts me into my own little reality where I can just sit down. While being relaxed and just messing with different things . I've been learning a lot about Kali Linux and how to use and set up on my phone . I also have 3 different laptops I use as well . Where I learn is a app called programming hub. I have there life time membership I'm almost done with the ethical hacking part . I just feel if I was taught or at least. Chatted with another person about it I'd have a better understanding.
Sounds like you are smart and familiar with code/ operations.
Note: I know nothing about Kali Linux in specific so this will be generic advice
You are saying you want to make money fast, so I am assuming you are looking for a cash reserve to be able to take bigger swings.
I am also assuming fast means about at least $5K-$10K/Month in 6-12 Months.
Here is one route you can take (Building a services agency route):
Step 1:
Find real-world applications using whatever skillset you have. Whether that is linux, solidity etc. etc.
Honestly, even something as easy as Python+ APIs have a lot of real world applications so I can't imagine what those languages have.
Step 2:
Find companies that need these applications. These could be SAAS companies / Startups / Recently Growing companies.
Try to find something that is specific and valuable.
Step 3:
Offer to work for 3 companies for FREE in exchange for case studies + referrals. (THIS IS VERY IMPORTANT).
This is important because you will make a lot of mistakes and you will learn. This will also help you get started
Step 4:
Start charging people for this. At this point you will be in Month 2. Start with smaller monthly fees
Step 5:
Continue charging more
If you do this and are actually good at what you offer, you should be touching 5-10K / Month in 6-12 Months easily

. Maybe even more
If you are serious about this -> Get started, find what you are offering, (Do step 1 and step 2) and then send me a PM.
I'll help you find the first few clients and point you toward the right resources.
