朱富置酒管待a。a道：“哥哥分付，教我不要吃酒，今日我已到乡里了，便吃两碗儿，打甚么鸟紧!”朱贵不敢阻当他，由他吃。当夜直吃到四更时分，安排些饭食，a吃了，趁五更晓星残月，霞光明朗，便投村里去。朱贵分付道：“休从小路去。只从大朴树转湾，投东大路，一直望百丈村去，便是董店东。……”a道：“我自从小路去，却不近?大路走，谁奈烦!”朱贵道：“小路走，多大虫，又有乘势夺包裹的剪径贼人。”a应道：“我却怕甚鸟!”戴上毡笠儿，提了朴刀，挎了腰刀，别了朱贵、朱富，便出门投百丈村来。

    Often people receive a guitar, mandolin, or some other musical instrument as a birthday or Christmas gift. There's joy everywhere. The giver of the gift knows how much the receiver wants to learn this instrument and the receiver is actually holding it in his hands instead of longing for it through the shop window.

    Finding an instructor that fits into a busy work schedule is hard enough, but once you decide on a lesson plan, then you must consider the practice time, how to practice, what to practice—and let's face it...not all people learn something the same way. So in order to learn a musical instrument, how much practice time is enough and what kind of practice is right for you?

    There is no set amount of time that anyone should practice a musical instrument. When I was in programming classes, I could have studied nightly for 5 hours each night. It would have taken me years to learn the art of computer programming. Though I'm attracted by the systematic logic of it, my talent is towards another thing. However, on the other hand, if I spent an hour every couple days with a passionate hobby like playing the violin, not only would the time fly quickly...I'd also be learning at a much greater speed since the built-in passion is the motivation for advancement.

    So as much as it's important to practice, a step back is to first find the harmonious instrument that fits you as a person; as development of your personality. If you're learning the guitar because it's cool....obviously that's the modern-day mindset, however, you might not be actually linking your talent for musical satisfaction with your most creative advantages you have to offer.

    It's been my experience that every person has a certain level of musical talent. My pleasant challenge has been to assist them in this adventure and actually locate their best abilities as quickly as possible. Then and only then can we match learners with instruments and truly begin a fun and exciting walk down the road of happiness and contentment, where music, ability, personality and soul all meet. Once this piece of the mystery puzzle is in place, I've never had to work at motivating a learner to practice...
