今朝放蕩思無涯。In high spirits, my heart is now free of any strains.

春風得意馬蹄疾，In the spring breeze, I let go of my horse galloping in Changan.

一日看盡長安花。How I wish with one day I could view all of its flowers.

PS Mr. Meng Jiao finally passed the imperial examination at 46 after so many misfortunes; no wonder he was on cloud nine when he heard of the good news.  FYI, his most popular poem is that well-known 遊子吟.
