Time is what seperates you and death. We should all use the time we have in the best way we can possibly think of. Spending time on things that does not achieve or ad value to your live is probably time waisted.

Think about it this way. You get to grow 80. But you have spend 30 years of those 80 years doing something you really hate or just did not like.
That means you actually only have 50 years of you life that you really lived and enjoyed.

Deathbed.

The best way to learn about life and having no regrets is to listen to old people just before they die. They would usually say if asked “I wish I had more fun” or some would say “I wish I took more chances”. Difference people would say different things. This is the best place to learn from other people.

Family.

One of the biggest regrets people have when their children grow up is that they which they had spend more time with them when they were younger. They grow up so quickly and if you are to busy you might just miss out on one of the most important things in life.

Faith.

This is probably the biggest and most important thing in life. Depending what you do in this life depends where you will spend eternity.
Difference.

Knowing the difference between what really matters and what does not is also one of the keys to living a happy life. Check what is important to you, what you would like to achieve in life. Does your goals have any value in them, would they make you a better person? Or would you just have the feeling of accomplishment when you have achieved that which you are dreaming about.
Explore.

Many people work their lives away, they dont see much of their families and they dont enjoy their jobs. That is really depressing. Exploring different ways you can lead your life to improve both your productivity and your time usuage will benefit you most in the long run.
Dreams.

You know that movie when the chick is about to die and then she spends all her cash doing the things she really wanted to do all her life? Well that is really what we should be doing. We should digg out the fun things in life and do those things we would enjoy and would brighten up our lives. We should live as if today was the last day.

Achievements.

People think because they are rich they have achieved everything in life, they chase after money their entire life and when they finally get it they realise that money wont make them happy. The fact is money can buy you luxury and all the possesions you really want. But money or achievements can not make you happy. When you close your eyes and you die, the things that really matter will only be realised then. The best way is to try and figure that out now. While you are alive.
Conclusion.

Have fun in life and think what you do before you attempt a goal.
