An Aries man is curious every day, he will always be the first to do something new. Complete with charismatic personality and leadership skills. He spends the morning working on a new approach with his trainer in the gym. Starting a new project in the office or beginning a novel writing initiative. The second biggest shortcoming of Aries men is their stubbornness. Their biggest flaw is their stubbornness. They are impatient and lose their cool very quickly. They come to conclusions and make decisions without thinking even for a minute.
