One important lesson I have learned in life is that every person should have one hobby and one labor of love in his life aside from his usual responsibilities of family, children, friends and career.
Hobby can be anything which you thoroughly enjoy like writing, reading, movies, playing golf, travelling, gardening or knitting - to sooth and numb yourself. (No facebook and twitter is not a hobby)
One labor of love is something which requires your dedication, affection, time and effort to any project like volunteering at any homeless center, teaching at church/mosque, part of any fund raising for good cause, going to cancer hospital to act like a clown for kids or any cause which is dear to your heart.
