Spiritual cost-benefit analysis
If you feel that you must seek something, do not seek knowledge, seek realization. Not necessarily self realization, realization of any kind. Realization MAY be still at your disposal after you pass away, knowledge of any kind will vanish with the wind.
This is a matter of simple cost-benefit calculation.
There is a lot of knowledge around because there are a lot of knowers around wishing to sell their knowhow, not necessarily in return for material possessions or money.
Realization is harder to seek and to find because it is not an object of the mind, because words cannot convey it, because others cannot present it to you, the most they can do is to point with their hands towards a direction, which is not too much because they always point towards your heart and you have already known it.
Realization is like love, except of the fact that this time you are completely alone.
If you feel that you must seek something, do not seek knowledge, seek realization. But remember that even this realization MAY NOT be at your disposal after you pass away.
