Impossible goal: financial freedom

More than anything, I want to have a nest egg I can live off should I need to. At least $2.5 million if I will live on 4% of that. It feels impossible to accumulate that much money in one year.

It also feels impossible to earn $1 million.

Is it better to pick 1) accumulate $2.5million in assets or 2) earn $1 million?

Thanks for your help!
