Studying while working

I recently realized how futile it is....ie to study while working....
First of all office work is usually 10-12 hrs which makes it very difficult to get time for studying...even if you restrict your office work (ofcourse sacrificing your performance as well...ur next review is gone!!)makes you mentally so tired that you cannot think of anything but sleep when you go to back to home...and opening a book makes u more tired...
And if you have a slight social life or home life then getting time is even more difficult...every now and then someone will want something from you and doing all those things will drain you...
Another issue is that you usually cannot disclose openly at work that you are studying because of obvious ramifications...and due to time problem you will usually won't be joining any classes (may be weekend classes..but that too are difficult...)...So most probably you are studying alone with almost zero friends with similar interest...
as a result you cannot discuss anything with anybody...you have to purchase all your materials and you don't know what is good & useful and what is not...only good thing is that since you are working you have money to purchase stuff you need...:-)...but that doesnt help because you can't purchase all the stuff..then you realize how good college days were...

So all in all it's almost impossible to study...

Morale of the story is once working concentrate on working and dont think about studying along with it...someone wise has said...having 2 legs in 2 boats will surely sink you...
