I have a friend who is a good guy who helps me out with things but he repeats different business ideas in the exact same manner as the last one and says i should get on board. It's always the same pitch with different concepts. I told him I'd join him the first few times but then i realized this is some kind of weird habit he has. He never actually initiates any of these ideas and he bounces back and forth between the ideas, makes an excuse why he can't carry out an idea and then forgets that excuse and starts circling back to that idea a couple weeks later and then something else comes up. I've seen him do this with other people and ideas too. He gets kind of offended since i don't really take him seriously anymore. How should i handle it when he brings these things up? I've tried to help him by saying things pretty directly like, "Look, you've been talking about X for a year. Why not get to it already?"

He's also talked about joining a gym for over a year and constantly researches gyms in our city online. I tell him "What are you joining a gym for? you've been talking about joining a gym for a year. You should find one that focuses on what you'll do there" and it's like he malfunctions and doesn't say anything.
