When you're alive, not many people care about you. When you're gone, even fewer will remember you. So, you must remember: apart from illness, all the pain you feel comes from your emotions, not reality.
What you need to care about now boils down to three things: your wealth, your health, and your inner peace.
The secret to staying happy is: don’t take things too seriously, let it be, care less, and know when to stop. Once your inner world is calm, the external world will fall silent.
