Complieting of sentence~!

I left early because I have to finish somthing to work. It was very expensive, but it was worth the cost. They never come on time , so I refer to discuss about making the rules of time and promise. There was train strike, so I should to drive every commute but I can understand them and I pary for their good life. I'll do it when I have the license of supervisor in couseling and I start the course of PH. D. It is opening my center of psychotherpy.
