There's a good ol' sayin' in the Fallout universe which also applies to the real world, more specifically 'Hard work is happy work'. If you love what you're doing (i.e. your job or jobs), you're gonna be happy about it, no doubt! In point of fact, the secret here, if there is any secret at all, is that a hard, productive worker might not even perceive work as such but rather as play.

This is something which will totally change your mindset in life, for those of you who have an ambiguous look on work; it's still play/game, folks! Don't get fooled by samsara or maya in other words, heh! Regardless of how hard your life might seem at some point, remember, it is just a game, albeit a more difficult one at times, but still a game, folks! And what do most gamers do? They play to win! Exactly!

Experienced, veteran gamers will even want to raise the stakes a bit and thereby ask it far more difficult, for the sheer reason that they got tired of playing on sandbox, easy, or medium levels.
Last but not least, one should also bear in mind that productivity is game/life changer. Therefore, I thought you might like the following informative and thorough video on Youtube created and uploaded by Freedom In Thought regarding how to be 10 times more productive than you usually are. Enjoy!
P.S.: Today's my birthday and I'm officially 24 years old and I'm still working. Yes, on my birthday and I'm very happy about it! :)
