If opportunity doesn't knock, build a door. Don't be one of the people who sit idly by and wait for opportunity to find a door to pound on, make your own door and your own opportunities if none are already waiting for you. Some of the biggest opportunity are those that you seek out, these will not just fall into your lap while you are waiting and life is passing you by. It is easiest to find opportunity when you are actively searching for it. Don't spend all of your time in the past, looking back with regret, or in some imagined future where you succeed without having to work hard and earn the achievements that you hope for. Be proactive and make the most of what you have right now while always looking for better opportunities to come along. Many opportunities are made, not simply found. Look at your skills and the unique talents that you have to offer. Determine what you want to do with your life and what makes you happiest. Once you have done this you may be surprised at the opportunities that you have, or the ones that you can make with just a little effort on your part.
