if today I make a choice to do my job poorly, have fun, play, and relax, then I will inevitably lose to someone who will work hard and disciplined at this time  

and this thought comes to me every time I turn on a computer game, or have a drink with friends

And I understand that I don't want to lose, I don't want to be a loser

And I won't be one

A combination of my sheer indefagitability, and my unequalled perspicacity makes me a feared adversary, regardless of field of endeavour

It's important to find a balance between work and relaxation. Remember, taking breaks and having fun is essential for your well-being and productivity. Just make sure not to let it interfere with your responsibilities. You can enjoy your free time and still succeed in your endeavors.
