The answer is very, very simple.
Stop watching Youtube/Netflix/movies every night. Forget drinking with friends after work. Kill WhatsApp, Facebook Messenger, and sliding into the DM’s of your favorite eGirl. Tell your family to respect your working hours during these months. That includes your wife, girlfriend, children and parents.
Put those hours into making something real with the programming language you love instead.
You’ll be an awesome engineer in 6 months. Not nine.
You have to sacrifice something to gain another thing. And that sacrifice means you will be so much more useful later on after doing it.
