when you experience failure, it does not mean you are in the final point. then do not you despair. so too when you are successful. it also doesn't mean final. therefore when you are successful, do not be arrogant, and consider yourself to be successful forever.
Many things will happen in the future without you expecting. maybe you are now living in pleasure because of your success. but that does not mean in the future you will be in the same position. maybe in the mass ahead you will experience failure. Likewise when you are experiencing failure at this time.
this is life. many things that you unexpectedly happen. the conclusion is keep trying. keep on showing the best things. and pray.
