Stress is caused by chaotic thoughts and ideas that have not been properly processed.
If we learn how to properly perceive, process and organize these thoughts we can gain clarity and recapture lost energy.
Meditation is great relax, remove motion and judgement from your concern and give you energy in the day, which is like sleep at night.
You can positive think something, but can U stop the brain thinking and let the brain take a break beside sleep ? Meditation is the best idea to recharge the brain if U can mast it. Try it, it can give U a total different experience.
