Dig back in time to when you were 10 years old. If you can't remember what it felt like to be 10, try 11 or 12. Remember the bliss of ignorance to the world around you. If you ever had stress, it was so minute, and could be managed by simply playing a game you enjoyed, or hearing somebody tell you everything was going to be alright. It's often that ignorance is seen as a negative word. Now for right now, lets not think of this type of ignorance as a bad thing. There are scenarios where ignorance can be a good thing. This may be a stretch... but it is important to your own wellness to not channel in on negatives, you may see people that seem as if they do this too often; you may look at them as ignorant people. But this, I believe is the good ignorance. The important thing to note is. As long as nobody around you is being effected in a negative way, be ignorant to negatives that have no value for the present.
There are negatives that have value for the present however. If you are driving through a terrible storm, you don't want to have a smile on your face and whistle your way through it and pretend it isn't happening. These negatives are neccessary to acknowledge to keep you safe. The problem is letting future negatives affect your present. If you are very nervous and upset about a terrible storm that is going to come tomorrow, you are simply upset about something that doesn't even exist yet.
Bottom line and cheesy moral. If you can constantly live in the present without letting thoughts of the future or past burden you, you can live the perfect life. While no life is perfect, remember to let the future happen, and let the past reflect a positive present.
