Everytime I thought about getting older and felt a little sad about it I just remembered that if I didn't get older I wouldn't be able to enjoy the growth of my own kids. I have loved being a part of something so rewarding and difficult as motherhood and so I have to love my new age at all stages. You will love being 30 and then 39 will give you a pang, but you'll get over it and think 40's are the best! It's really weird but true!
