user9846: As studies says 10,000 hours of practice usually makes an expert in your field, be it athletes, musician, doctors, engineers or any profession.
So I was wondering if I start doing 10 days course every month and practice 10 hours of meditation daily, so it will take 8.33 years to complete 10000 hours of meditation, which may not enlighten me but for sure it should make me an Expert.
How logical is that because I really want to know myself more, and I know that story of boy asked how much time will it take and master said 10 years and then he said what if i do more hard work he said then it will take 20 years, what is the essence here.

"Now, if anyone would develop these four frames of reference in this
  way for seven years, one of two fruits can be expected for him: either
  gnosis right here & now, or — if there be any remnant of
  clinging-sustenance — non-return.
"Let alone seven years. If anyone would develop these four frames of
  reference in this way for six years... five... four... three... two
  years... one year... seven months... six months... five... four...
  three... two months... one month... half a month, one of two fruits
  can be expected for him: either gnosis right here & now, or — if there
  be any remnant of clinging-sustenance — non-return.
"Let alone half a month. If anyone would develop these four frames of
  reference in this way for seven days, one of two fruits can be
  expected for him: either gnosis right here & now, or — if there be any
  remnant of clinging-sustenance — non-return.
"'This is the direct path for the purification of beings, for the
  overcoming of sorrow & lamentation, for the disappearance of pain &
  distress, for the attainment of the right method, & for the
  realization of Unbinding — in other words, the four frames of
  reference.' Thus was it said, and in reference to this was it said."
That is what the Blessed One said. Gratified, the monks delighted in
  the Blessed One's words. DN 22

So basically, depends on the individual!

user-1: I think you are coming at this from the wrong place.  Enlightenment isn't something that we add to ourselves.  It's best not to approach meditation as another skill to master or the dharma as another field where we might gain expertise.  It really doesn't make sense to count your practice in hours, days, or years.  Buddhism isn't a transaction - it's an offering that can't be measured by any metric.  Ultimately, there is no upper limit to how much we can sacrifice ourselves.
