Depends. Personal spending node? Pretty much braindead easy.

Routing node?
It is still a pain the ass. You can certainly make it profitable - until you get absolutely wrecked by FCs and other bugs.
I had mine dialed in and routing lots of volume, generating decent profit, at the cost of more or less daily monitoring and channel management. It's a part time job.

Then the november/december fee spikes happened and FCs around that time cost me around a million sats.
