Convinced to finish my driving instructor training

Having a good relationship with the employer is very important. I have read a lot of articles and books containing solutions about how to take care of a good relationship with your boss. I have always tried to apply all the wisdom in real life but I think I didnt manage eventually. I got fired two weeks ago and dont know what to do now. There was no actual purpose for firing me I guess. Maybe making somebody redundant was just a must for the company, maybe the profits and loss account was too low somehow and the expenditures had to be minimized. I dont know and...moreover - I dont care. Now I am trying to get back on tracks with my career. I am refreshing some old qualifications I got as a youngster to use them today. A friend offered my taking part in driving instructor training he organizes. He claims this is a very interesting undertaking and gives quite nice perspectives for the future job. I was not really convinced and wanted to know everything about it, so he explained it to me step by step. I got to know that all it takes is a couple of hours of the actual driving instructor training on roads, than a practice theory test and the final theory test to grant me the certificate. Now I am convinced to try and finish that driving instructor training quickly.
