It’s true that some people have an easier path. It starts right at birth, eg born to good family, no serious health issues, no disabilities, born into a safe neighbourhood, opportunities at a good school, etc. Or unlucky to get all the opposites. And then stuff happens in life, a lot of which we can’t control. The good and bad stuff is not evenly distributed. Some people get lots of good, some lots of bad, most of us get some of each. All you can do is make the best of the cards you’re dealt. That’s it. It’s normal to be more cautious and pessimistic if you’ve had a lot of bad stuff happen. The trick is to find ways to move forward, and say to yourself each day is a new day.
