Starting a Blog

Time flies.  In a blink 40 years of adulthood goes by. We were all told this in our teens, but.......

So I have taken the task of starting a blog on the experience of getting older. In itself, writing a blog for me will be difficult, laying it on the line for all to see. I have no experience in writing, but I do have experiences, some good and some bad to draw upon.

Do I write long or short ?
Do I add pictures or not ?
Funny or serious ?

This in itself will be an experience. Can I do it ? Can anyone without any writing background do this ?

Will there be an improvement over time?  Constructive criticism
is welcome-----maybe.

Till next time
