Your rating is a useful way of finding opponents of a similar ability. The difference between two ratings tells you the difference in ability of the two players, with the higher rated player having a greater chance of winning. If you find you are always losing it means you are mostly playing people who are better than you. Play people of a similar rating and you should win as many games as you lose. For most of us, our wins to losses ratio says little about our ability and more about the opponents we choose.  

To increase your rating you need to get better, and that usually takes time.
