A lot of things has been created by man, some were beneficial while others were not, everything does have advantages and disadvantages. However some of the creations of man has more disadvantages than the benefits. For example the use of a nuclear bomb is still unclear as it will possibly destroy anything in its path. Alot of problems has been created by man and also solved by man but how long shall we continue to leave in a world without future planning, if the nuclear bomb was to fall into the hands of the evil, the technology might be used in even more harmful ways.
The brain is very powerful as it creates just as it destroys. The human brain should be developed in such a way that positive thoughts surpasses the negative, over thinking is bad for the health however, not thinking is bad for the health and life as it weakens the brain power and gives you poor level of understanding. Just the right amount of thinking is good for any decision you are to be making.
As humans we need to take alot of things into considerations before taking decisions, as the solution today might be the cause of a problem tomorrow. We don't need to be hasty about our decisions as every step we take now is either going to make tomorrow better or worse.
Thank you for your time.
