執: seize the day

執, take hold, grasp:  At happy 幸 hour, there's a free round of drinks, so I take hold of mine.
摯, gift:                     Reach out hand and take hold of a gift.
Note about that second one:  it's listed as 常用漢字, but I can't find it in Henshall's index and Wiktionary doesn't (yet) have a definition for it in the Japanese subheading.  Whassup をわかりません。
執摯
