I recently bought a pair of pants very similar to this that came with a hideous belt which I immediately removed. It never occurred to me to replace it with a leather one. There's nothing sadder than exposed belt loops. My first instinct was to wear a longer shirt but the most interesting part of the pants is the top. Problem solved.
This is why it's important to constantly be reading, researching, talking to people, and hopefully discovering things that were previously outside your sphere of knowledge. It doesn't necessarily just have to do with fashion. Start with an idea "I want to invest in real estate" and from there every waking moment should be spent trying to draw a correlation between everything you see and hear and your new goal. You will never cease to be amazed at how far off and how close by knowledge can hide, patiently waiting for you to go looking for it.
