The more you don't care about the result,the more thoughtless you are,the result will be surprisingly good.
On the contrary,the more nervous and concerned you are,the more often something goes wrong,making you feel depressed and discouraged.
This is the so-called careless usefulness.
To put it bluntly,it is "heartless" to do things,do not care,do not get involved,just do your part,the result will naturally be close to you.
Don't worry about the trifles and forget the unimportant thoughts.
Empty yourself and focus on the present.
