On 7/31/2012, my son called in the evening. He was going to tell his boss the next day that the end of August would be his last day with the company.
I asked him why he gave the company a month instead of normal two-week notice. He said it would take more than a month for him to transfer over his projects. It would be more responsible if he could hand over his work smoothly to the next person.
I applaud for his courage and confidence to quit a good-paid job and go on his own. Meanwhile, I wish him good luck.
