您好亲！enjoy myself 和 enjoy oneself 都是享受、快乐和激动的意思，都包括个人的感受和经验，但它们之前有微小的差异。
enjoy myself 通常用于第一人称，指的是自己感受到的快乐、愉悦、享受等。比如说：
I enjoyed myself at the concert last night.
She always enjoys herself when she goes shopping.
而 enjoy oneself 则是第三人称称谓，指的是任何人都可能感受到的快乐、愉悦、享受等等。例如：
Everyone enjoyed themselves at the party.
The children are really enjoying themselves playing in the park.
总之，这两个表达方式的差别很小，这两个短语可以互换，都可以用于形容个人或集体的感觉和细微的差异。
希望能够帮到您。谢谢！
