Decision making!

Human's life is full of moments that require us to make our choices. Not like animals, our choices affect our lives dramtically as we live longer than the animals. When a lion see a deer, what the lion has to choose is to eat or not to eat.Even the lion regrets later or even for the rest of its life, it will be only 10 years to 20 years. However when a human made a decision and regret afterward, it may haunted him/her for 50 years, 70 years or even more.

As for myself, although i am only 21++ years old, there were a lot of mistakes that i had made, the decisions that i regret of. Sad to say, some of the decisions-mistakes will affect me for the rest of my life. I would do anything to make the situations different again. I would do anything to make sure i would not make another wrong decision again. However, life is not that simple. Once you choose, the consequences will follow you for the rest of your lives not matter what you do to change the situation. There are not such thing that once you lost you can start from the beginning. What you can do is only open another path from the path that you had chosen but the past will still be there no matter how hard you try. Some of the people may say :" Why we have to remember the things that you had done wrongly while you already turn to a new leaf?"

Well, we didn't choose to remember, but the human brain is not like a hard disk. You can delete the info that you do not want in hard disk but the human brain is something that is totally different. The harder you try to forget the harder you remember.

I am nearly graduate(1 years ++), i have to make another decision again. I am still wondering. Should i work first or should i continue my study. If i choose to continue my study, which area should i choose? Educational or Clinical? Would i want to be a educational psychologist or a clicical psychologist? If i choose to be clinical psychologist, there will be another choices that i have to make- whether i become a clinical child psychologist or i only want to see adult patients?
Friends, give me some opinions!!
