If you know you have to move from negative to positive, that right there is taking stock of yourself/introversion. Congratulations, you are doing well!

I would take a piece of paper and make a pair of lists, one titled "negative" and one, "positive" and have at it. On the negative side I would list what I do not like about my life or self and on the positive I would list what I would like or ways to try and change whatever negative I have on the left, opposite.

I see my medical doctor July 20 and so a couple days ago I decided first thing each morning I am going to figure out what I consider my biggest health challenge for the day and what I am going to do to work on it. Yesterday, for example, was my day for going out for pizza and I sometimes drink too much beer those nights. So, I decided I was going to drink a bottle of water before I went to the restaurant so I would not be at all thirsty, would be a bit liquid full and I was going to order the "small" size beer, instead of the usual "large" and I was only going to have two smalls instead of two large and a small.

This morning I woke up achy and did some online research and decided I may be dehydrated. So, today I am drinking at least 64 ounces of water (8, 8 oz. glasses; 4, 16 oz. bottles) and I'll see how I feel tomorrow when I wake by comparison. Alcohol/beer dehydrates (the liver needs the water to process the alcohol which your brain normally has claim to; that's what gives a hangover, especially the headache). Sometimes I get a headache just after I go to sleep but last night I just got more and more achy as the night progressed.

Just pick one thing each day you'd like to try to improve your life. Paying attention will call a bluff to the "I don't know how" problem, every time I have a beer now I'll be thinking about proper hydration
