Carpe diem!

The phrase "Carpe diem!" comes from the final line of Carmen 1:11, written around 23 BC. In the poem's context, it is an exhortation to use the limited time of life today and not rely on the next day. According to Wikipedia.

 It's the completely natural course of life. We come and go. But that sounds too dramatic and abstract. What isn't abstract is if I want to do something specific today and don't want to postpone it until tomorrow for any important reason. Or, what you can do today, don't postpone until tomorrow.

The diary is good for your health

Why is that?
Keeping a diary means relaxing from everyday life and letting go of what's happened as soon as it's written down. Regular journaling can strengthen the immune system, prevent illness, and reduce stress. It can have a similar effect to jogging or even meditation. By writing down events, we become clearer about our feelings. Thoughts can be revisited. The result is more balance and improved self-esteem.

And there's no need for an expensive, elaborate notebook. Any small note book will suffice. Another advantage is that you can "monitor" yourself excellently. What about those resolutions last year? And there's nothing more exciting than embarking on a journey into yourself. Try reading your diary from five years ago...
