I have tried setting time aside every day for prayer and meditation. It's something I learned to do from my father -- he does it faithfully each and every day and you can see how much it helps him.
There have been times, (like when I was living with my last boyfriend!) when I didn't do this. It was too difficult, too draining, to do it with him around, when he would whine too much and too often for me to get any real meditation or contemplation accomplished.
Then, when I was living alone, I tried to do it but my mind would wander too much, jump too much, when it would refuse to allow me to examine my own thoughts.
Now I am back to doing it pretty regularly... it grounds me... it reminds me to look at my thoughts and my actions... to be aware of them...
To allow my mind to quiety down.
But it can be difficult.
