There is indeed a common misuse of 'myself' these days, even by TV announcers!
The simplest way to avoid misuse of 'myself in a sentence is to follow the following advice:
Myself is a reflexive or stressed pronoun, which means that, generally speaking, it should be used in conjunction with the subject pronoun I, not instead of the object pronoun me. It can therefore be used properly in the following example circumstances:
I bought myself a car.So, if there isn't an 'I' in the sentence it is probably best to avoid using 'myself' in it.
I myself started the company. (Though even here it might be considered superfluous)
I did the laundry by myself.
I feel like myself again.
Tired of waiting, I just did it myself.
For myself, I prefer not to be invited.
