Hi. Please help. Which is correct? One day, this thought came to me and wonder if it is correctly written.<br/><br/>1. Once you think defeated, you are already defeated.<br/><br/>2. Once you thought you were defeated, you are already defeated.<br/><br/>3. Once you thought you were defeated, you were already defeated.<br/><br/>4. If you think defeated, you are already defeated.<br/><br/>5. If you thought you were defeated, you are already defeated.<br/><br/>6. If you thought you were defeated, you were already defeated.
