Life is an eternal struggle. But we have a misconception that struggle is bad. We need struggles to overcome. For example if you saw everything in the world be peaceful and good, you'd start searching for the bad without even knowing it, and if there is no bad things to find, you will create it for yourself in your head. humans need struggle and enemies to have motivation to live. struggles to overcome. We need purpose, but unfortunately when we can't find purpose in life we numb ourselves with pleasure and then have withdrawal problem when we decide to get our shit together. Struggle on friends, you don't have to have huge impact on the world, after all you can't stop a river with a single little rock, but strive to be better and change little things in life to better while also guiding other lost people. If you want books/philosophy to read I'd advice stoicism related material.
