Am I too old for this?

For years I’ve been toying with the idea of joining a religious order. But I’m 40. I’ve been working for the Church my whole career and I feel called some days and then don’t feel the call other days. Am I too old? I’m really not ready yet to talk to the vocations director so I’m asking advice here. What would it entail at this point in life? Does my “life experience” (lol) count for anything? Would it take as long as a younger priest-to-be coming out of college? Any advice would be helpful.
