1) Instead of going to uni for something useless I should have study IT, Computer Science and learn how to code and get good at it.
2) Be more motivated, less passive and take all the opportunities I had in my life to be able to make money and be in better financial position right now.
3) Move out from Russia long time ago or at least before this war happened.
Even a single of these 3 things would never make me even think about suicide in the first place let alone being here.
