The first teeth you get immediately after birth just like you get your first opinions from your parents and social environment. Later in life you develop your own opinions just like you lose your original teeth (called milk teeth) and develop more permanent ones that are probably gonna last you a lifetime.
It’s also a healthy habit to not feel compulsed to have an opinuon on everything. I’ve made a conscious effort to only form opinions on things that I perceive to be truly important. It has saved me so much stress.
