Do not rephrase the conversation.

OP said he would aim to step into the ring in 12 months , a noble goal, you rubbished this goal and said 3-4 months is the right time without knowing anything about the person, health, skill or other commitments, why are you back tracking on your original statements.

What is your reasoning if a man is a certain age he should put on some gloves and get in the ring, I know plenty of 50yo men should they compete in a bout in 12 weeks what is the logic in that.
I also know a few 27yo who like to drink 7 days a week, should I enter them in a show.

Your comments were to my eyes demoralising and un-constructive.

I would tread more lightly when you advise people to just go for it doesn't matter if you get beat, think long term.
