You know what? I love helping people, I also love how it makes them smile when I do something nice for them. It sure makes a difference in someone's life when you do an act of random kindness to them, or what I like to call an "ARK." Not only does it make them happy, it also give you an awesome, nice, warm, and tingly sensation when you do because you know you've made a differance(

Don't worry about it being a huge thing, it could be something as simple as a smile, a hug, a freindly 'hello', or even just being there. Sometimes all it takes is being a friend or a kindly neighbor who's willing to listen. While although some of us have all the time and the means to do anything for anyone in our lives, or that we encounter, many of us can't seem to even scrape by. So it doesn't mean you need to right away, after all, family first. There's a prophet in the Book of Mormon: Another Testament of Jesus Christ that really bashes on the men for not taking care of their families (Jacob 2). Another man (this time a king who's name is Benjamin) says that we should give to others when we can, and desire to when we can't(Mosiah 4:24). So please strengthen your family and when you can do service for others, including your family.
