A 28-year-old Harvard student once told Warren Buffett that he planned to join a consulting firm, reasoning that "it would look better on my resume."

Buffett's response was concise and powerful: "Isn't that like saving sex for old age?"

He then offered his own advice — choose a job you would stick with even if you were already financially free. Because that is the career you truly love and can achieve success in.

This advice was validated by his own experience. In his early years, he worked for Benjamin Graham for many years almost without pay, simply because his passion for investing exceeded his desire for a salary. When career choices align with personal interests, success often follows naturally.
