You will be thrilled to see how much your writing improves if you put in as much time as you did in learning how to multiply or ride your bike or apply mascara.  If you are serious about recording the significant events in your life, schedule a regular appointment with your computer or notepad. Keep it.  Writing regularly is one of the few healthy addictions.  Write every day, your body chemistry will tell you the time.  Not everything you produce will work, but often you will have to write through the weeds to find the seeds planted long ago.
