What is the most significant trading sacrifice you believe you have made?

If you have been full-time into trading for one to three years, what has been the greatest sacrifice you've made to become a successful trader? And did it pay off?

Someone I know who is a seven-figure trader has now made the sacrifice of moving into a shared apartment with a friend just to save money. Another person, who had previously started a logistics company, sold off his trucks and used the money for trading. Another person had to pay to be mentored. He did this because the mentor said people do not appreciate free things, and if he were not making the sacrifice of paying out of pocket, he probably would not be serious and would take it for granted. These people cited in here went on to become successful traders. It paid off.
