A simple way of describing one of the core teaching of buddhism is one of the main reason we suffer is: We are constantly neurotically pulling for what we want, and pushing away what we don't want.
It means as a juggles we are constantly trying to juggle our live into a state from where we think will be fullfilled. For example once I create this successful company, not feel hungry, then I will experience meaning satisfaction. Or when Im loved, or when I have a beer etc...
It's a never ending neurotic cycle. And the West is especially good at it by being extremely success focused.
Buddhism gives you tools to break this habit, and allows for meaning to be experienced in every moment (without this forced concept of YOU HAVE TO BE MINDFULL).
This doesn't mean you don't have all these personal things that should and can be improved, but the neurotic unhapiness leaves the experience of it.
It's often interesting to see intitially buddhist techniques, like meditations, being only used in a success/goal oriented mindset: will make you more productive, succesfull etc. where only a small benefit of the initial exercise remains.
