Early retirement is not the solution to any problem. That's the best way to look at it.
Early retirement doesn't solve your job problem. Your job is itself a solution to the problem of how you will not starve, of how you will not freeze and be rained on, of how to provide these things for your family or perhaps others you care about.
Early retirement is the Freedom to
As that, anyone pursuing early retirement as a solution to working is trying to be rid of a healthy and important part of life. All you really provide yourself by retiring early is the opportunity to finish the sentence, which means please, pursue early retirement in contemplation of what your freedom will be used to do.
Even if you choose a job with all its failings and all its merits, your choice to apply your freedom to it will change your time immensely. Happiness is not merely an absence of stress. Quitting your job won't make you happy, even if it's possible your job makes you miserable. Whatever you chase in retirement, let it challenge you to be the better version of yourself, whether it's connecting with people in 100 countries or building houses or reading at a nursing home or gardening or spending time with your children or grandchildren.
