a promise to myself and my child

Fortunately we were able to give my child everything I thought he needed (swing, bouncer, brand diaper bag,crib, stroller, car seat , etc) at only the age of 18 and 20. Now that we have our own apartment we can't buy him everything I wish we could, new toys and clothes. I really have to think about buying him toys/clothes or paying a bill. Thankfully my cousin has a baby acouple months older and had given us all the clothes and toys he longer uses. 
I promise to get my AA next year and get my bachelors diploma. I promise to work hard and get a good job and not have to hesitate to buy my son things I believe he deserves. I promise to not bring another child into this world until I know I have an option between buying a 1000 stroller or a $300( of course I personally would get the $300, it's just an example). I don't want my child to have to want something and be scared to ask because they know we don't have enough for it. 
Because nothing is worse than wanting to buy our son things and not being able to because you are short on money. 
I am writing this not for any of one else to prossibly critize, but to tell someone because I know if i would tell anyone that actually knows me they would laugh and judge me. 
What is your promise?
