You really need to detach yourself emotionally from work. You need act less with emotions and more rationality.<p>When people promise something x in the future, without any official contract I automatically assume that its not going to arrive. It&#x27;s just carrot. Expect the worst, and be a bit stoic. In many ways less gain now, is better than larger potential gain later because of the risk you take.<p>Don&#x27;t try to forcefully negotiate, or use ultimatums without any BATNA. When he broke his promise, don&#x27;t say anything. Find another offer, come back and say I have offer x now, bye. Maybe he will give a counter-offer if he really cared.<p>I&#x27;ve learned this from experience.
