هل يجب عليك تعلم أن تعطي الأخرين أكثر مما تأخذ منهم؟

لا. في حالة اذلم يكن العمل يستحق الإهتمام 

As Long as it is "knowledge", you can give them all what you have.. But time is also important.

There is a saying I know " The more you give, the more you get". Be Wise about it though, If you have something worth of value, people will and always run after you.
