Strong sense of self-protection, is this good?

A strong sense of self-protection is a good thing, but excessive self-protection will lead to suspicion of everyone and distrust of others. This is tantamount to closing yourself! Try to trust others. As long as you really trust others, everyone you meet will be trustworthy. According to the law of attraction, the more you doubt, the easier it is to meet people with ulterior motives. On the contrary, if you open your heart and embrace everything, everything will be better. Personally, I suggest you look at the law of secret attraction.
