Big thoughts and big actions. Do them together and you can certainly make your dreams come alive. This process is simple and direct, as you just need to apply the law of manifestation.
The size of your thinking determines the greatness you are going to achieve in life. Think small and you will live small. The guts and dare to think big, you are going to achieve a whole new level of results. Dream of a small car in life then that's what you are going to receive. Desire more and willing to work to get that more, you are going to get more.
Emotions and feelings are the motivation fuel. Your feelings of "I want this very badly" will spur your commitment and determination to a level that would allow you to push past your limits and comfort zone to reach your goals. Search deep inside you to truly understand the reasons "WHY" you need to reach those goals. Once you understand them, pen your goals down on paper to create an impression in your subconscious mind.
Following that, take BIG actions that correspond to your great and big thoughts! If you are searching for your dream house, see how much it costs and plan it out on how to obtain the dream house of yours. Dream and visualize about your dream house everyday. In this way, it activates the law of attraction and simultaneously you start to attract people and events that relates to your thoughts. Stay alert for "coincidences" from the universe -- for example, suddenly meeting an architect or anyone who can help you get that dream house.
Keep an open mind when it comes to your strategies and action plan. If you find your strategies are not getting you to where you want to be. Change! However, bear in mind that you only change your plans and not you goals. It's easy to give up when the going gets tough but it takes commitment, determination and guts to persist and ultimately succeed. Remember, when the going gets tough, the tough gets going!
