With the brain being the complex organ it is, our thought process will, however, at some point, stray to the negative - assuming you are positively inclined for the most part. To offset this possibility, and to get back on track should it occur, a good framework from which to encourage a healthy mindset is required to ensure you remain as sound of mind as you are of body.
If we see the world in negative terms - the so-called half glass viewpoint - this perspective is sure to result in negative consequences for much of what we do. A positive mindset, on the other hand, will provide a richly rewarding life.
To fully grow as individuals we must develop a mindset that is attuned to building a thorough understanding of any situation in which we find ourselves. Confusion and misunderstanding are breeding grounds for indecision, anger and self-doubt - factors associated with faulty thinking and negative thought patterns.
Therefore, before judging any situation, or problem, it is best to step back and place yourself in the shoes of those involved; gather a complete picture of what has occurred to determine what has happened and why based on objective observation rather than pre-conceived notions and prejudices.
For example, being upset at someone for not responding to a call may lead you to conclude this person is not reliable, and not worthy of your time. A multitude of reasons, however, could be given for why this person did not return the call - car problems, unforeseen work or family commitments, inability to receive the call and so on.
Blaming this person will only serve to foster an attitude of blame, which will lend itself to anger, self-doubt and indecision. A mind receptive to positive thoughts is able to fully analyze a given situation to gain a complete understanding. Determine the cause before jumping to conclusions and your mind will be free to form an understanding of what really happened.
Using positive thinking to continually reinforce why we are doing something is a major step toward the strengthening of mind that results in sharp mental focus, as opposed to disorganized thinking.
People with few aspirations and little motivation to overcome fear and undertake new challenges usually lack focus. Focus, at its highest level, requires total awareness of what you are doing and a complete understanding of why.
A total commitment to accomplishing your goal is needed, and complete buy-in to what you are doing is essential. This involves having a vested interest in the task at hand; the more significant the project, the more at stake as far as what you will gain from applying total focus.
Think it, want it, do it!
