Work on improving yourself, instead of wasting time feeling sorry that you are not the way you would like.
Describe your ideal self: What type of person do you really want to be? Be as specific as possible. Don't use vague terms like "being a kind person, gaining lots of knowledge, and being successful." With these terms you will not have a clear criteria to determine if you have reached the goals.
If, for example, you wish to improve in doing kindness, clarify the specific acts of kindness you plan to do, and how often. Then, once you have a picture of your ideal self, you can plan ways to travel the path leading to that ideal.
I also am working on my weight issue. I have finally learned the idea of portion control. Before I would just eat and eat because it tasted good, and I love all foods (I can't think of many foods I don't like) and would try to control by calories by not eating sweets and cakes.I learned it didn't work, becaue I kept getting fatter and fatter. I remembered the weight watchers program where they charged you twice as much for 1/2 the food, and I know it worked. So I tried it myself for free. In four months I have given back to the universe 30 pounds (I didn't say I lost it, becaue I don't want to find the pounds again, I gave them back to the universe.). I am now under 200 and going back to my ideal weight of 180. When I was an athlete I was 160 but that required hours of exercise every day. I am satistied that 180 will keep my healthy as I increase my exercise. 180 is doable in the next six months and then I realize I have to watch myself every day for the rest of my life as I picture my ideal self.
