Thinking Thoughts

What is so wrong with thinking a thought?
I guess it depends on what is & what is not,
Pleasant memories arrive in my mind,
A thought that is encouraging & kind,
Almost as if I need to reach for them,
Yet it feels good to remember when,
Sure, some thoughts are not so good,
Although there is a way that I could,
Search for the times, bringing a smile,
To find peace with my past for a while,
It’s good to be in the present moment,
I feel there is no reason to condone it,
Even visualization & hoping in the future,
To view life as a blessing, as we all mature.
