You want to make more money? Increase your net worth? What does it take? I'm starting to learn that skills - the right skills - are what will give you the competitive edge that you need.
Whatever the market wants is where you want to focus your learning. The idea is to have multiple skills, and although it isn't something that will happen overnight, it's worth the return on your investment. You could sell houses for three years, refinish hardwood floors for eight, then be an inspector for two, and still be above your competition. See, the thing is that the more abilities you acquire, the more you become an extremely rare commodity in the market because not only do you now have a network of connections, but you also have the skills to get the job done right.
Always work on improving your skills - the more you know, the more valuable you are.
