Waking up once and for all is exhausting if you are so used to snoozing that alarm. So you snooze 2017, and you might snooze 2018, and live your life on snooze, bored and missing out on the day, and unable to sleep at night.
It is always wonderful to hear somebody, almost everybody saying that they want to improve something about themselves or their lives. It stops being so wonderful, when the resolution becomes a broken record every year. It becomes sad when you keep postponing, and pathetic when the excuses are shined and dusted anew every year. So just do one thing for now. Just one tiny little change in your life, and it will snowball beyond your imagination.
