No one should push you to do anything. It is you who should push yourself.  
You know what you are capable of, but you also don’t realize how much more you are capable of doing, until you push yourself. 
There is so much more in you than you know. When push comes to shove, you will see all that you are capable of. 
That is why we have problems and situations that test us, so we can bring out what is hidden inside of us, and use it. We are more capable and powerful than we know, and we find this out when we are challenged, and when the going gets tough. 
Never complain about hard times, for those are the times that your power comes through, and you actually amaze yourself at what you are capable of accomplishing. The hard times are what forge you into a Stronger You.
