Please tell me only if u know any true life steps to gaining inner power and strength?

After watching DBZ and growing up on DBZ cartoons I have become infatuated with the thought of creating energy bombs with the energy in my body like on the show. Another example is the spirit gun technique from Yu Yu Hakusho. After reading some of Newton's laws on energy I have found that energy is neither created nor destroyed. In real life, would this knowledge hinder the characters of DBZ and make their attack methods impossible? (This is just for fun. Don't leave any insulting posts, please.)
