Feeling the baby blues?

So I don't know if it's my age, if I've reached that time in my life where my biological clock has started ticking, or if I'm just feeling pressure because everyone I seem to know is popping out babies or is about to.  Lately it's something I can't seem to get off my mind, no matter how hard I try.  I've always wanted to be a mom, since I was old enough to like boys pretty much, but I have yet to just settle down and do it.
There is always excuses for not having children, oh I'm not ready yet, I need more money, timing isn't right, etc.  If we all waited for the perfect time, I don't think there would be as many children as there is.  If we all waited to have the perfect financial income, obviously again, there would not be as many children running around.  The last one timing, well this might have some meaning behind it.  Timing is important, you don't necessarily want a baby with the wrong person or when you really are not ready.  Having kids in a relationship that is doomed to fail, or with someone you are just ok with probably shouldn't be considered, but again these are only my opinions and thoughts on the subject.  It is not only hard on a child be shoved from parent to parent every other weekend, but I think a child should get the privilege some of us never had growing up, the ability to grow up with a mother and father to love and care for them and provide for them. 
A child is a beautiful thing and some of us are meant to be mothers and some not so much.  That is for no one to decide of course, I mean that there are some moms out there that have a hard time with it, weren't ready or just happened at the wrong time.  Then there are some of us that can't wait but can't seem to get it together.    I don't think there will ever be a perfect time for motherhood for most people.  I just know that I want it in my near future.  I am 30 years old and time seems to be going quicker the older I get.
For those out there who are mothers and read this, can you give advice or encouragement?  Were you scared to become a mom, was it planned or unplanned?  Do you wish you would have waited or was it something you were excited happened?  I just want incite from other mothers...all ages and their experiences of motherhood.  I believe it will help me in my future goals and how I go about my future goal.
