Balance
There are several principles about life that I believe. I believe that the key in life is balance. That your life is the best when it is balanced. Not too much of anything. For example, not to much work or you will miss the finer things in life. Not too much fun and play for you will become lazy and feel inadequate. Plus, when there is work to be done and it is ignored, it doesn't go away. Balance in what you put in your body. I do not believe in diets just eating correctly and being smart. A balance in a relationship. A balance of time spent with them. It is important that while in any relationship there is balance and space is available. One thing that I feel girls do not do enough in relationships is let their boyfriend have fun with his boys. Seriously, guys need that time to be silly, cause trouble, be loud and run around. Girls need their own time to, sometimes you just need to be with your own gender. The best relationships are when there is a balance. When each love each other the same amount. When one doesn't feel more benefited by the relationship than the other, but both feel their life is better with the other person in it. Balanced is needed or your life will be sideways. A lot of unhappiness can come from a life without balance. Set priorities on different aspects of your life and find a happy median.
Happiness
First, I think that many times unhappiness comes from being stagnant. The feeling of sitting in a row boat in the middle of the pond but not moving, and for a long time you are sitting there in the middle of the algae green pond, and the bugs begin to buzz around your head. And until you pick up that oar and starting rowing the bugs will continue to buzz. To be happy one needs to be constantly evolving and moving forward. Having that feeling of accomplishment and necessity. This can be a tricky situation, a person can be moving forward and still unhappy because of too high of expectations. Someone may never be satisfied. Yet moving forward and refining to be the best can bring a lot of happiness. I believe that part of this evolution and or growing is education, constantly striving to learn and broaden the spectrum of knowledge. To become a more aware person, to have the ability to think for oneself. Too many people rely on the opinions of others, not taking the time to put serious thought in their formed opinions of the world. I have seen far too many situations where people believe the media and their biases. Be your own person, think for yourself.
One of the ways that I find happiness is serving others, finding ways to help and serve. I feel the world becomes more and more selfish.
Time
Time is remarkable concept. It never seems to go at the speed that one desires. Time drags on when you are bored, anxious, upset, yet speeds by when times are the best. I believe that time does heal everything. And that at the moment of the episode all looks lost and hopeless. But as time moves forward both parties move on and the pain settles. I have experienced the bitterness and the darkness of depression. Not being able to see happiness. Feeling like I don't have the energy to move forward. But family and friends help you find that lost light. It takes time to forget, it takes time to heal. It takes time to completely understand why. And sometimes we never completely understand.
Carl Sandburg describes time as a coin, time is the coin of your life. It is the only coin you have, and only you can determine how it will be spent. Be careful lest you let other people spend it for you.
And of course wise words from Gandalf "All we have to decide is what to do with the time that is given us"
