[1]Everyone wants something in life, love, money, success and so on. Yet too many people fail to achieve their goals, and nearly all of them are for the same reason.

[2]It‘s true that terrible things do happen to people during their lives, though no fault of their own, which may make them feel upset. Generally speaking, however, getting what you really want out of life is just a matter of the following three simple steps.

[3]Firstly, you have to decide what it is you want the most. But do not make a list of wishes; try to focus on one thing at a time. If you‘re not sure about where you want to go, you‘d better think it over first and not hurry to perform.

[4]Secondly, create an action plan. This will be your map for getting from ”____________________” to ”where you want to go”. You know what you want, and what steps you are going to take to get it. For example, if you want a better job, start with a skills assessment and maybe some extra training. Then you‘ll need to sell yourself and your skills either to your present employer or to a new employer.

[5]Other goals will require a bit more thought. Some will really get you lost without a clue of how to get there. Not to worry, though, books, biographies and such, can be of great help.

[6]The third and final step is to execute. Do what you planned. Take the steps you outlined on your road map and keep going on all the time. If you run into some people who are against you, simply ignore them.

[7]Never give up the goal. Keep pushing. Whatever you do, do not lose heart until you have what you desire in your hands. Never think that you can’t turn your dream into a reality.
