That seems pretty harsh. It also seems pretty accurate.
"It is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is able to adapt to and to adjust best to the changing environment in which it finds itself" Charles Darwin
Our attitude is what must change for us to overcome those things that may "kill" us. Our inability to reach our goals is often a result of our inability to change our attitude from an attitude of negativity, victimization and despair to an attitude of gratefulness, joy and optimism.
"Your life does not get better by chance, it gets better by change.” Jim Rohn
