Overthinking will only ruin yourself. Some things are beyond your control, so just go with the flow, take it one step at a time, and who knows, life might just become smooth sailing. Don't have too many worries, and don't let a single issue affect you for too long. Don't make yourself live so exhaustively every day; as long as the sun can rise as usual, there are no obstacles in life that cannot be overcome. Even if life is messy right now, strive to make it colorful. Don't think too much, just live in the moment, and as time goes by, you will find the answers.
