You're looking down on the people at the bottom or middle of the mountain, struggling up hill to reach the peak, and wondering "why are they going through all this effort? Why don't they just stroll around on flat ground like I am?".
They're still building the systems that you already have in place. It's far easier to use a system you already have than to build one from scratch. Maybe not with physical or academic health for you, but I'm sure there's some areas of life that you're lacking in that could use improvements. If you can't think of any, I can give you a hint: empathy. If you try to work on it, you might have to do things like set reminders to call friends on their birthdays, or just to check in. You might have to force yourself outside to chat with that neighbor that you don't exactly like and find some common ground. You might have to set a goal of volunteering a certain amount of time at a homeless shelter, and track those hours.
Meanwhile, there are people who already have buffed up their empathy their entire life, and do all these things(and more) naturally.
Should they look at you and wonder why empathy is so hard for you, and tell you your efforts to consciously improve this part of your life is a waste, since they were able to achieve higher levels of empathy without doing any of those things ?
