Happy the man, and happy he alone,
He who can call today his own:
He who, secure within, can say
Tomorrow do thy worst, for I have lived today.
Be fair or foul, rain or shine
The joys I have possessed, in spit of fate, our mine.
Not heaven itself, upon the past has power,
But what has been, has been, and I have had my hour.
Horace
Ode
I believe you can live everyday like that. We always tend to focus on what we lack, or the things in life that surround us, that cause us problems, and not much time is giving to thinking about what makes us happy, we will always want more, we will never get it all and we will never get everything done.
Take a moment everyday to see what you do have, if you think you don't have much then you don't, what makes you smile, is there a memory that cheers you up, no? then visualise and follow that, feel it, breath it, do it everyday.
