Daf Yomi - Sukkah 13 - See your world in your lifetime

The Gemara discusses a situation where one is disturbed by leaves falling into the Sukkah and this will cause one to exit the Sukkah. For this reason one should not use thornbushes for s’chach. It is noteworthy that the Torah commands us to dwell in the Sukkah for seven days. Yet, it is not sufficient that one build a Sukkah that will remain standing for seven days. One must also ensure that all the materials that are used in the construction of the Sukkah are acceptable so he will not have a reason to exit the Sukkah prematurely. In a similar vein, the Gemara in a number of instances uses the expression that a person was yotzei min olamo, meaning that he left his world. One is granted a finite amount of time to accomplish his purpose in this world, and one should ensure that his ‘accommodations’ are established correctly so he will not be required to ‘exit’ before his allotted time. This idea is reflected in the Gemara in Brachos 17a that states that when students would depart from their teacher, they would say to each other, “may you see your world in your lifetime.” This statement can be interpreted to mean that one should see his accomplishments in this world, i.e. he should lead a full and productive life.
