In the workplace, it is important to choose between tolerance and leaving, as staying without compromise can make it difficult to stand firm. If the situation becomes unbearable, it is best to leave and find a new job. Losing a job is not a big deal, as there are always other opportunities. Sometimes, leaving a job can lead to finding a better one. 

It is essential to be tough in the workplace to succeed. Choosing to be tough does not mean being cruel to others, but rather protecting oneself and thriving. One should learn to be assertive and not always be a people pleaser. Here are three key points to keep in mind: 

1. Prioritize and protect your own interests. In the workplace, there are no permanent bosses or colleagues, only eternal interests.

It is crucial to continuously seek better opportunities and learn more for personal career development. Remember that you are there to earn money for yourself, and the company hired you to create value for them. Focus on discussing financial matters and never compromise your own interests. 

2. In the face of colleagues who harm your interests, be decisive in confronting them.
