A person thinks about 50,000 to 70,000 thoughts a day. If you try to "catch" them, you'll see that not all of them are positive and empowering. Actually, you may find a majority of them are negative and limiting. Now, if we take into account that our thoughts lead to our feelings that lead to our actions that lead to results in our lives, we can say that our thoughts create our lives, which makes being aware of them even more important. This way we can start using them to our advantage.
Where do they come from and why are they so hard to control?
Negative thoughts come from our subconscious mind, which stores memories from the past. All traumas, defeats, stressful moments, bad news we read or heard about, etc., got stored in our subconsious. When we're in a situation that reminds us in some way of an unpleasant past experience, it will do its best to "get us out of there" and keep us from feeling the unpleasant, sometimes painful emotions we felt in that past situation. It will try to persuade us that the new opportunity that may have come up for us and which at first seemed so exciting isn't "safe". You know the little voice in your head that keeps telling you: "This isn't right for me", "I don't have time", "I'm not going there", "I'm not good enough at it", "I'll do it next time", "It's too risky", etc.
It's interesting how we rarely doubt the "truth" of our thoughts telling us we're not capable, not good enough, not smart, pretty, young enough, etc. But when we become aware of the fact that these "truths" are based on past experiences and we are not the same person we were back then (new experiences, new knowledge, etc.), we can allow ourselves to doubt them and choose other, more empowering ones.
For example: Imagine you get a call from a tourist agency, telling you you were picked as the winner of a one-week holiday in Hawaii. If you are afraid of flying, you might get excited at first, but the very next second you'll find a number of excuses why you cannot accept the offer.
How can EFT help?
When we think a negative thought, it creates a negative emotion (e.g. flying by plain). This negative emotion is actually a disruption in the energy system of our body. By tapping on acupressure points we eliminate that energy disruption and no longer feel the fear (the negative emotion). As a result we make different decisions, undertake different actions (e.g. we accept the agency's offer), which lead to different results (e.g. a coctail on a Hawaiian beach).
Keep in mind that your life mirrors your thoughts and beliefs. Think of an area of your life that you would like to improve orchange, but don't seem to be able to. What's holding you back? What is your "inner dialogue"? What are you telling yourself? Analize your thoughts. Find proof that you're right or that you're wrong. Even by doing just that you'll be able to eliminate many negative thoughts.
Or you can decide to take the easier way...EFT or tapping :)
However you do it, I wish you many pleasant, positive, empowering thoughs!
