Regardless of external happenings around you, your genetic makeup or background which you had no control over, you can turn your life into something great by focusing on the things you have control over. You will always have control over three things: the thoughts you think, the images you visualise and the actions you take.
The quality of these areas of your life will determine the quality of your entire life. If you are displeased with the current state of things, then alter it by altering one of the three components.
Whinning or playing the blame game will never improve your lot. Taking responsibility would.
