Isn't that a problem with expectations, rather than with philosophy?

A philosopher should not be biased; morals and ethics belong not in the minds of men, unlessing morality and ethics are what you are intending on arguing in the first place.

Philosophy examines what we have currently, and what we don't have, and then it contrasts those two things. The goal of philosophy is to attain a higher understanding of oneself and of everything around them, which requires a mundane amount of disappointment. That is why philosophy is probably man's worst enemy, we suffice with solace in the self-denigration of our world.

Only a fool would pursue philosophical matters. Questioning things that never were and never meant to be would be something only a fool would partake in. Which is why I love it even more.

I think it is a problem with the person rather than with philosophy itself.
Life is a constant 'problem' but that should not be a problem if you apply philosophy correctly.

Philosophy, an evolutionary drive, is the development of wisdom (knowledge & effective experience) to resolve problems.
That would include how to handle the problem of unresolved problems or impossible to solve problems.

Philosophy (not academic) should not be problematic if you understand what it is and how it should be developed and practiced.

In addition to the various sub-goals of philosophy, a control feedback loopshould be included in the main and sub-processes.
If your expectations are not met, then your control feedback loop should prompt you to review your objectives and the processes for changes and critical monitoring.

After going through the feedback loop 100, 1000 or 100,000 times where and if necessary, you would likely to get somewhere and confident that you know thyselfand philosophy.

I think what you're describing is only the beginning of philosophy, not the end of it. You are saying that the subject has been approached with certain expectations, and they didn't work out. Well that is part of what it takes to learn the practical discipline. Any philosophy worth its salt ought to be able to deal with disappointment.
