Stop being so wishy-washy! You’re being indecisive.

1. Natural and conversational:

Stop being so wishy-washy — make up your mind!

You’re being indecisive. Just choose already.


2. Slightly more formal:

You seem hesitant to make a decision.

You’re having trouble being decisive.


3. Emphatic / Persuasive:

Don’t be wishy-washy — stand firm on your decision.

Being indecisive won’t help. It’s time to commit.
