Welcome to Adulthood. I work nearly 60 hours a week - Monday to Friday. I'm up as early as 4am, and don't get home until atleast 11pm. So by when, the weekend rolls on: I'm shattered, and have no energy to go out socialise with mates, with the family taking up my priority.
In any case, my list of friends is as short as my pinky finger. Alhamdulillah, I've done very well for myself, in regards to my career and financial state. I've got a wonderful job, own my own home, and a full wallet - with money saved for a rainy day. For me to have achieved this, I've had to sacrifice my social life.
Sometimes, sacrifices like this, is needed.
