The power of the mind is so undeniable that many things that people normally experience have their base-root from the mind - that is their thoughts. If you have noticed closely, you will discover that most times, your actions are normally fashioned out after your most dominant thought. Even your words are also a reflection of what happens in your mind and the thoughts that go on there. No wonder it is emphatically stated in the holy book that:
From the abundance of what the mind thinks, the mouth speaks.

As much as your thought pattern influences the words you speak, it also influences the way you act. It is worthy to note that, as there are no idle words, so are actions resultant effects of thoughts. When you constantly think about a particular thing, it will not be long and it will form part of your subconscious memory and when that happens, your mind will tend to respond to the thoughts involuntarily. These thoughts are what will form the bedrock of your actions.
When actions are repeated from time to time, it will become part of the person's attitude and of course, you will agree with me that the summation of attitudes will give rise to one's character which is what conceives and nurtures the future. You see, all these extrapolations came basically from the mind. In order to have a good character that will nurture a great tomorrow for you, you will need to sow the right thoughts.
It does not matter what a farmer wishes, the kind of fruit he will harvest from his farm is a direct result of the kind of seed that he had initially planted. In a similar way, when you have a wrong thought, you cannot expect to magically have a right action and will obviously not have a right attitude nor a right character. The truth is, your tomorrow is at the mercies of your today's thoughts.
To be fair to life, we all have been gifted with a level of thinking faculty and the power of imagination. However, what you imagine is entirely your responsibility. Just like a farmer that goes to his farm to plant seeds, the power of imagination is like a seed and after it is planted through thoughts and actions, the results will be reaped.
The person that was able to conceive a big idea and ultimately achieves it does not have an unfair advantage from life, he only utilized his power of imagination and then worked with it. What differentiates the successful people from the others is in the usage of their power of imagination. If you use your imagination quite often, it will tend to be enhanced and more potent.

Just to let you know, even though thinking is a gift, but thinking positively is not a gift. That is, to think positively, you have to make the choice yourself without recourse to other factors like the prevailing situation. The only way you can combat a negative thought is by introducing a positive thought because you cannot bring in another negative thought to ward off a negative thought, otherwise your whole live will be full of negativities.
