Parenting tips and tricks?

I'm probably gonna be a dad. ( sadly at age 15) and I just want to be prepared cause I want him/her to do well in life and not be... Well me. I'm not saying I'm unfit for parenthood. I've made stupid decissions is all I'm saying. So any tip/ tricks. I've heard of one called the guilt trick. Things along those lines. Thnx for ur help.
