Grad school can be a great move. Grad school just to avoid deciding is an expensive pause.

More education is a real step forward when there is something specific on the other side of it. It is also the most respectable way to postpone a decision, which is why the reason matters more than the choice. The pause costs years and money while looking like progress to everyone watching. Nobody will question it, so you have to.

Write the sentence that finishes your plan: after this, I want to be doing a specific thing that requires it. If the sentence will not finish, that is worth knowing before you apply. Working for a year and applying later is nearly always possible.
