It likewise can be a recipe for misery to ignore the role of luck in your own life and the lives of others. It's not only inaccurate (sub luck out for the mechanisms by which the world turns), it attributes an unreasonable level of burden of consequence on the decision maker, one they can never hope to live up to and one no one around them will ever live up to.
Of course as with many things the most reasonable course of action is something in between. To both acknowledge the ways in which we understand the world works and how much of that is outside your control, and then take very real ownership of the things that are in your control (namely your actions), and take special care to note how taking control of the things you can over time ends up compounding in unforeseen ways such that you end up "luckier" (the meeting of hard work and opportunity and all that).
If anything this just seems to once again show that any extreme along nearly any axis is not only inaccurate but detrimental to mental health. Nuance and acknowledgement of opposing ideals, and realizing they're compatible and not actually opposing at all, is where one finds truth and solace.
