It depends. Some people have really weak philosophical foundations and really need to hear about it if there is something out there that grounds them a bit better.

We can't say if any particular approach to life is the best, but we can say that if you change your mind about which approach is best at age 70 you've spent a lot of years setting up for the wrong outcome. It is never to late in theory. But as a practical matter 70 is a bit late to sit down, take a step back, ask why and try to act on it. Better for people to line themselves up with good foundations from their 20s or maybe 30s. It is good to explore the options early, and think a bit about what the word 'option' even means philosophically.
