A new method deserves enough attempts to separate unfamiliarity from ineffectiveness.

Anything new feels worse at first, because you are slow at it while your old way is smooth from use. That awkwardness gets misread as evidence that the method is bad, and people abandon good approaches during the exact window when they were always going to be clumsy. Until the strangeness wears off, you are measuring your familiarity rather than the method.

Decide in advance how many attempts you owe it, and hold off judging until then. Keep notes on what specifically goes wrong. After the agreed number, drop it without guilt if it is still worse.
