Almost Tet (Lunar New Year Festival) in Vietnam, and so much to do with just a week to go! Let's use my time smartly! I hope discipline will jump on me from behind in the new year.
As always, I'm just trying to show you some new things. The way I wrote it, the first sentence has no verb. This is legal because it ends with an exclamation mark.
Rather than say "I will try", I said "Let's try". It is stylistically acceptable to say "we"/"us" instead of "I"/"me". Look up the "Royal 'We'". Traditionally, it was used by kings, but ordinary people can use it too. It is slightly humorous. Scientists and other academics often use the royal "we" in the articles they write. It is useful to them because it makes them sound less self centered.
The Italians have a humorous saying: "Desire to work - Jump on me from behind" that I like very much, so I thought I would share it with you in your last sentence.
(In Italian: "Voglia di lavorare, saltami addosso!")
