How do i follow god from my whole heart?

[Aaron]

Hey guys. Im 13 years old and i struggling with knowing if im following god with my whole heart or not,so ive done some internet searching and i think if im not lead to do what god wants me to do than im not pleasing him. I tell people about the will of god and the truth on how to get saved some laugh and rarely someone wants to know more, you know when your about to cry and you can feel your heart, i did that and thought about following god from your whole heart, so after i got done telling my friends on facebook,twitter, etc.I decieded to reachout to more people, so im making videogame in flash and sometimes i did what i always do make my heart open and started designing. but i rarely feel like im pleasing god. am i following god with my whole heart.
