Hi, " I was there yesterday ": this is a fact, and the verb is in the indicative mood (past simple tense: I was, you were, he/she/it was, we/you/they were). " If I were rich (I would quit my job and travel all over the world )": this is not a fact -- it's counterfactual (as I am not rich, I cannot leave my job! ), and the verb is in the subjunctive mood (past tense: I were, you were, he/she/it were, we/you/they were).

AnonymousIs it because of the 'if'?No, it's because it is subjunctive. For example: "If I was rude I am sorry" is correct, and, "If I were rude I am sorry" is nonsense because "was" refers to a real event, not a hypothesis.
