<human>: Could you distill the essence of the text into 1-3 sentences?

I've worked for a newly formed team for as long as it has been around and as it grew I grew too. The team is in-house and its clients are internal. That provides a difficulty in itself, but as the team is there to support others internally, we don't necessarily get 'juicy' work. We usually get the more routine based tasks. Here lies the problem. 
I have recently become a manager of a small group of people within this team. The team I'm in is seen by graduates as a bit of a stepping stone on to grander things, which isn't great and means that the retention in the team is low. The team is ambitious but this drive is focussed on what is after my team, not what is now. The 'routine' work we receive isn't enough to satiate them and this causes them to lash out demanding 'more training and better work!' It's difficult and I'd love to give them this 'better work', but we get what we get. There is some engagement with the rest of the company, but that is a slow process.    

We have a weekly 30 minute meeting. Last week I discussed that, although you might not be able to change the work you receive, you can change your attitude towards it. If you approach work with negative energy that is all you'll receive in return and vice versa. I told them that I couldn't force this change, it had to be a choice. The reaction I got was loud and angry. It took me off guard. There was a lot of accusation of no development, but that isn't the case. The point is, they're angry that we're not developing them for the next stage (which is nothing to do with us).    

I used to look forward to these 30 minute meetings, but right now I'm struggling to find a topic and finding it even harder to find the motivation. Any advice?
<bot>: Just became a manager, team is demotivated as the work we have is routine and 'unexciting', struggling to see what to do next.
