Deliberate thinking does not mean pretending.
You don’t have to say everything is perfect.
You just choose the direction.
Instead of: This is terrible
Say: This is hard, but I can handle it
Instead of: I can’t do this
Say: This will take effort
Instead of: This won’t work
Say: This may not work, so I’ll try another way
You are not lying.
You are choosing where your mind goes.
