There is no easy level
Different, unexpected things get harder
tl;dr
Wallowing and ruminating over how you think other people have it easier is guaranteed to make you miserable. Trust me.
Stewing in that sense of powerlessness actually decreases your motivation: when we think that life isn’t fair, we assume that our actions have less value.
We “move up” to different levels because of a trait called core self-evaluation, which measures our self-esteem, believe in our ability to figure things out, and emotional stability.
