It is not necessary. You don’t need to do it always. You don’t need to accept them. Fight!
What a big relief, isn’t it? You got the permission to fight! Go and happily fight, I tell you.
See, you are not required to do anything which you cannot do. Do only that which you can do. If accepting is so difficult, don’t do it. If not accepting it is easy, that is great; but if accepting it is easy, do that.
