I am able to do all things through him who strengthens me. ~ Philippians 4:13 CSB
Keep your can'ts to yourself. And for sure don't try to impose them on anyone else.
Be reasonable ... I'm not talking about wrong things, I'm talking about the ability to accomplish great things for The Kingdom and personally with God's Power. Don't share your can'ts with me or anyone else and don't give life to them by speaking them.
Focus on what The Word says. It's the Higher Truth in every circumstance. Bishop David Oyedepo got hold of this Word of Truth, and instructed his staff that they could never come to him saying they can't do something. They have to change their speech into a positive which forces them to change their thinking.
Here's an example. I say to you pay off your car loan this month. What are you thinking? I can't do that. Electric shock buzzer!!! You've already bound can't from your lips, so you shouldn't be thinking that. Instead you should be thinking, I can do that with Holy Spirit Resurrection Power in me and working through me. I have a book full of thousands of Promises that can't fail. With faith I can do this!
