Winning friends and influencing people may sound simple but it's an art in communication and confidence. The first step you can make today is not to complain, judge others or criticize people, even if it's justified. People do not like to be shown that they are wrong, especially if it ties into how they see themselves. People quickly become aggressive and resentful of the person calling them out. If your goal is to win them over, definitely avoid that.
Another important thing is to show others sincere and honest appreciation. People love to feel appreciated and will often do more for you at their expense in order to "pay you back" or make you happy. Another tip is to make the person want what we want. If you want someone to take over this task, instead of telling them to take over this task, you can make them want to do it on their own.
