Entrepreneurs make dozens of decisions every day. Often, we don't even think twice about the options laid out before us; we just instinctively choose. And yet there are so many variables affecting the choices we make, such as emotions, perceived outcome (risks and rewards), former experience or education, stress, and the list goes on.
Draw a hard line between the good choices and bad; there's no point mulling over things that just aren't good for you. Of course, you should always trust your gut. Your gut feeling is based on all of those previous experiences and intuitive feelings you may not understand or even remember, but it won't lead you astray.
