Someone will break a promise to you, which is disappointing. Don't let this setback stop you from crossing the finish line. You may have to submit an entry late or attend the last few minutes of a meeting, but take heart. Rallying in the midst of difficult circumstances will count in your favour. Someone else may get a job or scholarship, but you'll be in the running for the next opportunity. In the meantime, have an alternative plan ready when relying on others for help.More
