I spend a lots of time thinking about balance in life. I think the key is do what you love. If everybody in this world will do what he/she love, than he will be in balance. He will not work, he will spend his time doing, what he want...
Think about it. If you love your work, you will come to it with smile and you will looking forward on it.
If you love someone, you are enjoying every moment with him/her...
Key si love
