My heart is a little light now

Yesterday, I didn't have any appointments.

Therefore I did preparation for the job as a interpretor of this weekend.

Until now, I have some experiences as a interpretor at like casual party etc., however I have not had any experiences at formal place like this time.

Three months ago I got the offer, since then I have felt pressure and been nervous.

However I could prepare well yesterday, after that, my heart got a little light.
