I told some students about a plan I have for the future. I worry it could backfire long-term if we perhaps meet at a corporation for instance, perhaps after academy. As if confiding dooms me to be exploited, even if forgotten and appearing after a long time.

I want to take the plans. I read it makes it harder to take the plans when confiding them and it's true. But I can fight those feelings if I must.
However what concerns me as I mentioned, is its effects on competition on the long-term. How can I make sure to seal the "gateway" to me, so I'll be able to handle the competitions?
