Need some support please

So I'll start off by saying I just need some encouraging words right now. So I'm thinking of finally going to school to be a teacher. I know it'll be a while to finish but I can't get this feeling off that I should do it. I'm 27 and mom to a 7 year old little girl. I just want to give her the best life and I don't want to feel like I'm too old or it's too late for me to start this journey. Thanks for anyone that comments I really appreciate it I just really need some encouraging words 💖
