Living your life to the fullest means you do not waste any time. You plan your day well and prioritize doing things that matter most. Do not bury yourself in too much work. Yes you need to save money for the future, but remember that you are young now. You wont be that way forever. Allow yourself to experience everything that a person your age should be experiencing. Take time out of your busy schedule to do this. Also, allot some party budget for yourself to have a little fun now and then.
