How would you deal with this?

Still struggling with the new job. I find myself spending the day in meetings! No time to do the proper work that I have on my desk, but most of all no time to start puting my stamp on my team, as I need to.

The people in my team know their objectives. They know what we need to achieve, and what projects they have on their lap.
But they don't seem to move! They don't move and only wait for me to tell them what they need to do!!! I really struggle with this! I strongly think that more and more people need to think with their own head and get things moving. BEING PROACTIVE.
But what they are doing is complaining to each other... on how they are worried that they don't have a lot to do and are afraid that if there are job cuts they will be next... Come on!!! Grow up and do something about it!
I really feel like going to them and saying 'just bloody do something, just bloody move, it's your job, make something of it! Move, you know where you need to get to! So bloddy get on and start thinking how to get there! I'll be there to bounce ideas of, to unblock paths, to influence at higher lever, to secure budgets, to discuss and agree paths...'.
But if I am aggressive, I will just loose them, as they are quite fragile and with limited self confidence.

I am really annoyed but I guess this is the learning curve for managing people.

CURRENT LEARNING: I am being too nice. I need to be tougher on them and start demanding more. I need to hold them acocuntable more. To challenge them more. Set them targets. Set them clear objectives.
