Could elements of anxiety have benefits?

Anxiety is an extremely widespread disorder that most people will experience at least once in their lives; whether as a predisposition or one that manifests due to some kind of event experienced. On a day to day basis 70% percent of our thoughts are negative, this is an unfortunate statistic (it is amazing everyone does not suffer anxiety). Now if everyone had better control over their thoughts... or at least better control over the nature of their thoughts (allowing more positivity)  lives could potentially be lived without the burden of constant negativity.

A picture that I feel strongly conveys the difficult nature behind our thoughts  

Thoughts are a very hard concept to grasp, they are an innate phenomenon that practically control everything that is not done via automatic processes - such as breathing etc. However... from a biological perspective; thoughts and emotions are made up of energy, molecules, and axons which release vibrational frequencies. When the frequencies are low then they are transformed into low level emotions such as fear and guilt, but when high they are transformed into higher level emotions such as courage.Thanks to this kind of information we are now able to use strategies in order to convert the lower emotions into higher ones, such methods can include mindfulness and breathing techniques.

Now the symptomatology created through anxiety can be increasingly unpleasant, although experiencing them can in turn make you a stronger person, or help you to avoid experiencing them again. So instead of looking at anxiety as a barrier it should be perceived as premature wisdom; the only way to deal with hardships is by living through them. Mereley just paying attention to the reasons behind your anxiety can lay the foundation to overcoming it.

I personally feel that if used right, anxiety can be beneficial. However depending on one's lifestyle, support, and tools available to them it would be naive of me to think that everyone could possess such an outlook. I am a great believer in ones ability to take control of themselves and change for the better but some circumstances can make this philosophy somewhat difficult to comprehend.
