Ask to work overtime.  That way you do not need to stress about getting to a second job on time.

There is a site called Excellence-Success...read some of the articles about making extra money.

Since you have all of those skills and they are exceptional skills...why haven't you taken them somewhere to earn more money?

I can think of nothing as miserable as leaving one full time job and going to work another job...especially when earning extra money is as easy as asking for a raise or shopping your resume around to  companies that pay more.

But it is up to you.

Your analytical, etc, skills could help you in practically any business, but are not sufficient to base any business on. Your choice of second-income source is really up to you, your interests, abilities, talents, experience, etc. E.g. a lot of people in corporate jobs use their creative hobbies as a source of second income as this balances their creative side with the routine of their corporate job, as well as alleviating stress! E.g. handcarved wooden toys or kitchen implements by an talented woodcarver; handsewn or handknit or crocheted garments & accessories; a potter who sells their pottery; an artist who draws excellent & admired caricatures from someone's photo. Such choices depend on what hobbies you have, how good you are. A qualified corporate accountant might take on accounting (especially quarterly taxes) for a sole proprietor or small business. Some want a more passive income & research dropshipping options, develop a website, and sell a category of product they favor, have some knowledge of & experience with. If you want just a paycheck, and not the vagaries of your own biz, then find a part-time job weekends. E.g. an accountant might work for a tax preparation company during the season for some extra dough-re-mi. If you have such "great analytical skills," figure out what works for you!

Instead of working an extra 10 to 30 hours a week to earn an extra $10,000 or so per year, why don't you look for a job that will pay you $10,000 to $20,000 MORE per year than you are earning now but still lets you work the same hours?

Or ask for a raise.
