The question seems very serious when asked like that. But the answer is really quite simple. No matter how old you are, you need a time for yourself, you need a brake from everyday things. Let us take an example, you are at work, you give your best to finish all the work within given time and you succeed. Now, what could you treat yourself with when all your tasks for the day are finished. At least one hour of playing your favorite flash games online.
And why online? Because its convenient. Every descent company has a good Internet connection which allows you to easily access some of the best online gaming sites and proceed with your plan. Find, play and at the end bookmark your favorite free flash games. The next day you can do the same and it will most certainly make your work week much more amusing and can even be motivating. If you finish everything you need to do and you finish it earlier, there will be enough time for one quick play! Am I right or am I right! But there is a down side to this. Playing games during work hours is a very responsible thing.
Little contradictory you would think. No, I mean exactly what I said. Not everyone can responsably play games during work hours because it takes a little bit of effort not to turn your whole day into one long game play. People should realize that balance is everything. If you finish the work and treat games as an award they will give you even more pleasure. But if you can't stop playing than this is not a good idea for you to do. A friend of mine lost her job over this so I know exactly what I am talking about.
