إن شئت أن أنسى .. تذكرت
امتلأت بحاضري , وأخترت يوم
ولادتي .. لأرتب النسيان

Most often, the reason something is "on your mind" is that you want it to be different than it currently is, and yet:
• you haven't clarified exactly what the intended outcomes is;
• you haven't decided what the very next physical action step is;
• and/or you haven't put reminders of the outcome and the action required in a system you trust.
That's why it's on your mind.

إن شئت أن أنسى .. تذكرت، امتلأت بحاضري واخترت يوم أخر لولادتي .. لأرتب النسيان

My trouble was I had a mind but I couldn't make it up!

In my case, though I had an idea of what was going on - I purposely didn't see it.

Life must go on; I forget just why.

What you don't know may not hurt you, but what you don't remember always does.

There's a lot on my mind so I guess that I'll take it one thing at a time, still sometimes I can't help but wonder why...

First of all, if it's on your mind, your mind isn't clear. Anything you consider unfinished in any way must be captured in a trusted system outside your mind, or what I call a collection bucket, that you know you'll come back to regularly and sort through.

You recently had a day, or even a month, that you can’t remember.
If I asked what you did then, you couldn’t say.
There was nothing unusual about it.
