Way To Progress ...

If you are only doing what you CAN 

You will never be more than what you are NOW .. 

So for making progress what you need to do is 

just do those things what you can do and also do the things which you think you can't. 

If you are not trying something what you can't do 

                                                 you don't even know who you are ... 

because it is possible that you might end up thinking you can only be a good team member but not a good leader as you have never lead a team that is you are doing what you can but it might be possible that you end up as the best leader if you try , which you thought you can't. So, at least give it a try friends.
