As for oneself is a phrase commonly used when discussing personal beliefs or actions. However, there are several synonyms that can be used in its place depending on the context. For instance, instead of saying "as for oneself," one could use "as far as I'm concerned," "for my part," or "personally speaking". In a business setting, you might say "from my perspective" or "in my opinion" instead. In more formal situations, "in my humble opinion" or "as regards to me" could be appropriate alternatives. Ultimately, the choice of synonym depends on the tone and context of the conversation or piece of writing.
