This is that idea that you come up with or the opportunity that is presented to you that may look & sound good on the surface, but does not have enough facts to support its ability to succeed. It's a "shot in the dark" concept. As a business-builder, we know that a big part of pulling the trigger is KNOWING facts, not just hoping because it SEEMS like a good idea. Emotion is not permitted when making decisions in business, only factual researched evidence is. I will say that the good-bad opportunity is only acceptable when you're just starting out as an entrepreneur. Your time is not as valuable when you first begin and the lessons learned by trying new ideas & opportunities are invaluable to your success in the long run. Before you pursue a questionable opportunity, ask questions & do your homework. Know why you're doing it!
2) The stepping-stone opportunity
This is the opportunity that has a definite beginning and ending, realizing that it is simply serving as a catapult to a new and better opportunity, which will ultimately help you reach your long-term goals. The question you must ask yourself with this type of opportunity is: "what's worth more, the time & money I'm investing NOW or the final payoff that comes from the next chapter?" This is sometimes a risk because we can't know that everything will go as expected, but the deciding factor for taking on a stepping-stone opportunity is realizing the high probability that new & better opportunities will come out of it and that it's simply a means to an end. Again, understand the why's before making your final decision.
3) The home-run opportunity
This is the opportunity that just makes sense all the way around and fits in perfectly with your goals. It's the no-brainer concept that has facts to support it. This type of opportunity creates wealth while freeing your time to pursue your other ventures. This is not as common of an opportunity as the others, and for obvious reasons. If this is not your own idea, then it's likely that you have some solid value that you are bringing to the table since you were approached with it to begin with. This doesn't take a whole lot of thought when deciding to move forward with it.
