“She says she ca’n’t, oo know. But I thinks it isn’t ca’n’t, it’s wo’n’t.”
Most of the time, when I say, “I can’t”, I really mean, “I won’t” or “I don’t want to.”
With respect to other people: it’s just easier to say “I can’t” because it implies that even though I do want to, I am unable to. Of course, it makes it even easier because (usually) nobody calls my bluff.
The truth: I just don’t want to sound like a bitch. In most situations, I can do these things but I just don’t want to (for whatever reason).
On a more personal level: it makes it easier for me to justify to myself why I am not doing something I want to do. So, I tell myself that even though I want to do so-and-so, I can’t because of such-and-such reason. It implies that things/circumstances are beyond my control.
The truth: There is always a choice. There is (almost) nothing I can’t do but several things I won’t do. More often than not, it is because I am too afraid to do these things. It is just so much easier to make excuses than to go outside my comfort zone and actually do these things. It is so much easier to blame other people/the world than to come forward and take responsibility for my actions/omissions.
The only thing/person stopping me from doing exactly what I want to do is myself.
