All you can do is what you can do. Being realistic when it comes to exercise is the smart and safe way. There is pushing yourself and then there is overdoing it.

There have been months when I could do 2000+ and months when I am lucky to get 1000. It is important to be flexible and listen to your body. Some months are big numbers and some months are smaller numbers, both are good!
well said!

I wanted to also comment on how many people said there goals are small. I totally get where the sentiment is coming from, and there have definitely been times when I could have pushed myself harder, but if you set a realistic goal where you know you will have to work hard, but not overdo it, then that is the right goal for you. We can celebrate each other's successes no matter what the number.
