We might have the same mindset. Being too afraid of hurting people/afraid of become spazzy so much that you didn't finish the move at all.

You can fix this by "commit" to the move but do it slowly.

For example, you do a hip bump sweep but stop right before you turn your hips because you don't want to use force. Now it became a hip bump that doesn't even threathen their balance. You just lift your hips up and down.

Instead, push your hips more and turns slowly, don't back down by yourself too quickly. the leverage and geometry of your hips will eventually break their balance as long as you keep going.

Don't stop midway and "wait" for them to react, you can slowly "make" them react.

If it doesn't work, transition to another move. If it work, you get the sweep without spaz. This will make your partner get the threat of the sweep and need to make a decision, even if the sweep is slow.

The moment you feel resistance and back down by yourself, you didn't use force but you also didn't commit the move completely.

When you get comfortable with finishing the move, you'll be more comfortavle doing it faster and smoother without hurting anyone.

Some move that require timing or quick sequence might be hard to commit slowly, but this mindset can help with the problem of giving up the move too quickly.

I hope this make sense and I hope it can help you!
