Whereas a lot of Buddhism concerns itself with stages of enlightenment, various precepts and moral codes, and even power structures and hierarchies, Zen is just like, 'Shut up, sit down, and observe your thoughts - oh, and by the way, what you perceive as you' doesn't actually exist.' I loved the minimalist approach of it.
How do I control my emotions? How do I stop getting angry so often, or how do I stop being sad? And I think there's a really important distinction to understand is that you can't completely control your emotions. What you control is your reaction to your own emotions. And a lot of people don't ever make that separation for what goes on with them.
People want to start their own business or become financially independent. But you don't end up a successful entrepreneur unless you find a way to love the risk, the uncertainty, the repeated failures, and working insane hours on something you have no idea whether will be successful or not.
