I asked the same question when I was young and I decided to push it off until I was older. Looking back I wish I had taken the time to pursue my education so that I could be a greater asset to my current company and myself. I believe know that the sacrifice of 4 years or more is nothing when you put it against a life time of happiness and knowledge. Knowledge is the one thing that no one can ever take from your. Always strive to better yourself as it can only provide you with a brighter future.
