It's important to work hard, it's important to get everything that you want from your proffessional life, however, there's something more.
You have to spend time with the children, and with the important people on you life. They are more important than cars, career, big houses, nice clothes and any other material things. You don't need to buy those special people things, they will cherish the time spent with them, more than anything you have ever bought them.
This is why my daughter and I started the doll house project. We are building one together and building memories together at the same time. And, I am really enjoying it. (But don't tell any of my male friends!)
