If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age

No matter how smart a person is, he will be lost if he has more concerns; A fool may give advice to a wise man.
