Realistic goals to be set

So far, I have performed at least 10 minutes of exercise a day.  So far, I have been having fun with exercises on tape.  Maybe I should dance more or try more.  I do tend to say negative things about myself which is counterproductive.  I feel like I have lost some weight.  My weight is something that is of importance to me because of my health, fitness, and overall well-being.  I also tend to be hard on myself and that is why I tend to give up.  I would like to say is that I won't give up, but that is what I end up doing.  Well, the truth is, I would like to set realistic goals and for now, 10 minutes is a realistic goal.
