To be honest i learned patience, self motivation and scheduling things. For patience thing is sitting at home almsot doing nothing but still waiting calmly to be released from lockdown. Self motivation. I made myself get into sports. I did workout at home and made a lot of new recipies for dinner, invested in few games and made even 70euros from nothing :D Scheduling. As i said i was into sports so i had to know when to do my workout, when to eat dinner, when to do other work that were undone. I did all of that and still had free time to get some rest or play video games !
