The times in your life.
You have to enjoy the time at the time, you must enjoy your life while it is happening,
Savour each precious time together moment.
Hug your children and parents, as many times as possible, this is something you will never regret just glad you had the sense to do it. Tell your wife you love her and hug as many times as you can while you are still together.
It is too late to wish you had done these things earlier.
Live your life in each moment, it is old advice and sound, ask any old timers what they wished they had done, and guess what they will say.
Go ahead, get out there, and experience the good, bad, and the rest of the crap just remember it is your life and good luck with it.
