If you only can do twenty percent of something then practice doing it so you become the best you can at it.

   Trying to force yourself to do something just because other people say you should, can be setting yourself up for failure.

  Just because you don't have the "tools" to do something doesn't mean you can't do it.

  The "tools" you do have, if used correctly, can get the job done. 

  It might not get it done to the "standards" that others felt it should have been done. But you can still accomplish getting it done.

  No one is good at everything. As long as you do what you can do, the best you can do it, you will get the job done.

 Then when it is done you can celebrate your "I told you so" moment because you got it done.

  Then just get busy finding and doing whatever it takes to accomplish anything else you want to accomplish.

  You can't say you can't because you can do it. You just will have to do it however you need to.
