I have a paragraph as follows:
When you accept yourself as you are, you will be less prone to jealousy, worry, blame, guilt, regret, lies, insults, and even compliments. Thus, you will appear more certain (you will be more confident). For example, hearing compliments or insults from somebody else will not make any difference if you know yourself or trust your own opinion the most. So when you notice someone who reacts strongly to other people’s remarks, even compliments, they are nonconsciously admitting their lack of confidence and self-esteem. Besides being the simple thing to do, there are more benefits of accepting yourself unconditionally. Once you have good relationship with other people without having relied on any external value for your attractiveness, you also know for sure that they like you instead of your external value.
Can you explain the meaning of expression "Besides being the simple thing to do? Thank you!
