Thinking about changing my goal weight

My goal weight is 149 lbs. I set that goal when I first started losing weight. It seemed like a number that I would never be able to get to. Now that I am less than 20 lbs away from that weight I am thinking about changing my goal. In order to be in a healthy BMI I have to be 136 lbs or less. I want to be in the healthy BMI. I haven't decided what I want my ultimate goal weight to be. I know it is just a number and I wont really know where I want my weight to end up at until I get there but it still helps to have a number to shoot for. I am leaning toward 132 lbs. I wish I could see how I would look at 132 lbs right now so I could know for sure it that is what I want to be. Only time will tell I guess.
