If you think you don't have anything to do or achieve, you are living a purpose-less life which is not important to anyone! Goals are important to make life move. Life is not scripted, you write your life everyday with the help of your imagination, actions and feelings. Though everyone needs to live in present but needs to know where they want to go or what their purposes are!
When you have goals you can rise. You don't stuck at the moment rather you make ways to go forward. A focused mind can help you live a conscious life and that life moves with the goals. So have goals and create your life. have moments but don't get stuck. Move forward with your focused mind.
