I assume you mean ideas of what to work on rather than blocked on a particular problem. It's hard to this generalize to everyone, but for myself no, never. Actually the opposite. It flows like water and I have many more ideas that I can pursue at once. I don't start coding them all, rather I'll conduct layers of due dilligence and market research continually trying to separate what's promising from what's a rabbit hole. I have a whole process to try and make what I work on efficient and good risk/reward. When I was younger I'd just get interested in something and start. No more.
