Strength vs Weaknesses

I was thinking about strengths and weaknesses of individuals and found this quote:

“Success comes by strengthening your strengths more than improving on your weaknesses. If you can maximize the potential of your strength then you become a champion while if you work harder on your weaknesses you be come Jack of all trade.”

And I found it curious, because it goes against the accepted idea that one should on mitigating their weaknesses. But on the other hand several articles I found online state the same. At least when working with a team, one should rely on other people’s strengths, rather than fixing their own weaknesses.
