It may be lonely but it may not be as lonely as you think if you choose to be active in making life more meaningful through humanitarian or public service work. If you choose another career path then yes...you will probably be an outsider or face the possibility of abandoning your ideals in order to fit in.
Bill Hicks...quite a guy lol. I almost used one of his lines in a sig but it would probably have got me banned.
Good luck in whatever choice you make
