Some busy people always complain how busy they are. Some might even feel little proud of being busy. If you are busy, I think it’s better to ask yourself a question: “Why are you busy?”. If the answer is “school, work, hobbies, etc. – all the stuff I need to do” then you’ve responded wrong. You are busy because you’ve chosen to be busy. Nobody forced you to work or take so many classes or hobbies. You have put yourself in that situation, and it’s your responsibility to deal with it. Simply delegating work and learning to say “no” can help you.
Being busy is not because too much of work, being busy happens because of accepting and taking too much work.
