The most happy and successful people in the world are masters of sharing. The most unhappy and consistently challenged people, both emotionally and financially, are poor at sharing. When you find people who are alone and miserable, in most cases they are also not the sharing kind. When you encounter people who persistently are unemployed, or have difficulties getting ahead in their jobs, most of these people too will have problems with sharing. In fact, wherever you go in the world and whomever you meet, as a general rule the people who do the best in their careers and lives are good at sharing.
