A wise man only considers the the truly relevant facts when he makes a decision.
"Don't let artificial barriers get in the way." This is something my dad always told me. What are artificial barriers? Its anything that your mind or the culture, or any other entity puts in the way of the right decision that is not really important. Things like "I can't marry the girl I love because we're still in college" or "I can't get accepted into that research program because I won't get the application in on time" or "I can't exercise because I don't have enough time" could all be examples. Your mind can put artificial barriers in the way when you are uncomfortable with something, and others can put artificial pressure on you when they are not comfortable with it. If you want to do great things with your life, you need to push these things aside and be radical in making the best choices based on truly relevant facts. If you are late in getting that research program application in, petition the people in charge anyways. If you are passionate, they might let the deadline slide. If you know that you want to marry someone, but you're still in college, don't let only cultural norms stop you; it has worked many times before. If you have a good plan, don't let artificial barriers stop you. You can always come up with a reason not to do something, but wise people only consider what is truly important.
