The best life changing program?

Hello. I'm wondering which is the best program? I find myself always searching for new information when it comes down to pick up, because I am a shy guy with zero experience and also having social anxiety. I always tell myself that I have to change and have to take action, but when I do it for a week or two I just come back to my old habits - staying at home (I am introvert) watching TV and spending decent amount of time on the computer... I need program which can help me to push harder, because the years pass by really fast and here I am - eighteen years old with zero experience, knowing what I have to do but don't have enough motivation. Can anybody help me and sorry if there are any mistakes. :/
