Living positively

Isn't there a saying that goes something like, there are no shortcuts in life? What is it that makes people think that they can use shortcuts in life? I strongly believe in karma or destiny, that one has to give to get anything back, and if one thinks that one can just keep taking without giving anything back to life, then you're sadly mistaken. For a lot of kids, it's just the thrill of doing something that they're not meant to, and drug rehab centres are full of kids who thought they could get away with it. I think these centres are rightfully doing a lot of work on changing the way people think and changing their attitude and motivation towards life.
