I truly don’t get why we must endure so much suffering

Salaam, everyone. From what I understand, Islam is about making the right choices-avoiding theft, shunning lies, and standing up for what’s true. So why are we forced to go through so much pain? Why is life an endless stream of struggles and worry? Why does Allah test us at every moment? Everything feels so heavy. Can’t we just show we’re decent people without all this hardship?
