I'm hoping this doesn't sound trite or morose, as everybody says this kind of stuff when someone passes suddenly, but I'm going to give it a shot. Do it now. Whatever your "it" is, just do it now. None of us know how long any of us have, but we put off taking that Disney trip until the kids are older, or the economy is better, or until I lose more weight, or whatever. Just do it now. Call your dad and tell him you love him. Don't wait til Father's Day. Mend fences. Build bridges. Spread pixie dust. Just do it now.
