Patience can make the situation negotiate against itself.

Given time, a situation often applies its own pressure: the other party’s alternatives worsen, their costs mount, their internal disagreements surface. You do not have to generate that pressure yourself, and attempts to do so usually create resistance. Waiting lets the circumstances make your argument.

When you would otherwise push, consider stating your position once and then holding still. Let the situation develop. What you could not have obtained by pressing sometimes arrives on its own.
