Isn't mindfulness is difficult for a thinker which usually philosophers are?
Mindfulness by definition is bringing awareness to present moment non judgmentally and I agree it may relax you. I believe it happens because you shrink your attention to such a short span, in a moment by moment fashion that complex thoughts can't be formed and thus you relieve yourself from any unpleasant (or pleasant) feeling that may arise from complex thoughts. In simple words, you reduce your suffering, if any, to at it's minimum by limiting input to senses.
However, is avoiding complex unpleasant thought always desirable? aren't these thoughts and their uncomfortable feelings motivates and inspire us introspect and change?
For example: In early childhood I had my belief and respect for patriarchal social system(disbelief in gender equality). It were some uncomfortable thoughts that made me correct myself and disregard such systems which causes unnecessary man made suffering. If every time I felt uncomfortable and practiced mindfulness to avoid them, I might passively be supporting such system till date.
You may say some thoughts are useful and worth attention & others not. Like worrying about upcoming college exam won't do any good, you may just use best of the time left. However can we say that with 100% certainty? The worry is something bringing your attention and focus to a problem at hand, may be you could be one in a million who will get a brilliant idea to handle such situation or device a undetectable way to cheat, or it may just help to focus and put 100% to prep for exam or it could keep you panicking, unproductive and prove itself a useless thought pattern. Similarly if you fail on an exam, there is no good in being sad about it or is there? may be the sadness is useful in making a neural pattern in brain to put more effort and time next semester.
Hence I even find judging thoughts worthiness is difficult and inconsistent. However if you are having too many negative thoughts keeping you on the edge on a regular basis may end up in health issue, in which we can regard it as certainly a problem.
To summarize, wouldn't being too much mindful may make you too adaptive to be mal-adaptive? wouldn't it may stop your thought processes which might have produce some good for society? or simply stop you from growing intellectually?
Edit: I am trying to simplify the question as following:
Would a life, where each and every moment is lived by the technique of mindfulness, be nihilistic?
