Unlikely that you'll learn what you want by trial and error in a reasonable time frame, either.That being said, keep your money in your wallet for a while until you have a well thought-out, sustainable investing strategy and plan.

The truth is, you could read 100 books and still not know enough because certain things need to be learned through trial-and-error.

All the lessons are like diets, we all know we should be on one and know how to diet but neglect to do it even though we know it is the right thing to do.  

And how to do it won't come from a class, a book or a program, it takes trial and error and knowing your market and political issues.

@Shane Baum - Van Ed has a 7 day free trial that allows you to access the content, but not take any of their quizzes.

You'd want to identify the outliers.You'll really need to progress by trial and error.  

You need to feed elderly people meals with specific diets 3 times every day.

I'm among-st creating my own spreadsheet (Sorry BP, I did use yours but have ran out of free trials!)

Commercial development is in a league of its own, which I think working for a company or person in the beginning can definitely help out with the trial and error phase you will definitely go through.

After 2 years of legal tussle, in 2008 at trial (these things go very slowly) I was finally able to prevail.
