How to practice mindfulness How to practice mindfulness during the day?

I have been know known to be absent minded and forgetful but perhaps it's due to my Karma. The problem is so bad that is someone else makes the mistake due to their mindlessness I am automatically blamed without knowing the facts!!!!!

I have been told that meditation clears out ones' Karma and that mindfulness during the day is another form of meditation (I already sit on the floor Burmese pose 30 min twice daily and breathe in, breathe out)

How to gradually start being mindful? It seems rather overwhelming .... Thanks!
Start by adding Walking Meditation to your practice.

Next, when you finish your meditation and are about to go on with your day, make a resolve to be mindful and try to keep that mindfulness as you leave the meditation.

Then start setting aside key times during the day when you will accomplish some activity mindfully.  For instance, it could be meal-time, or a break in which you take a walk or do your exercise.

Gradually expand that mindfulness practice to include other parts of your day.

You could also carry a mindfulness timer or app that will chime at regular intervals to remind you to be mindful.

Most important: don't get discouraged.  Getting distracted or falling back into old patterns is natural.  Mindlessness is a habit, and like all habits, it takes work and there is backsliding.
