Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart. Steve Jobs
If you're scared of doing anything, ask yourself what's the worst thing that could happen if all goes wrong. Then compare that scenario to death. I bet you it's trivial in comparison.
Let's say you want to quit your job, start a business and follow your passion. What's the worst thing that could possibly happen?
Well, your project could fail, you could waste a bunch of money, and perhaps get into some debt if you're foolish about it. You would also gain invaluable experience. And you would have to get a new job, which could either be better or worse.
Now how does that compare to the destiny we all share? If you keep in mind that you're going to be dead soon, it's really not that big of a deal to risk your job security.
