Its hard

I understand there are different ways to look at things, for example if I think ‘it’s hard’ and it’s not be useful, I might change it to ‘What if it’s not hard?’ Or, ‘Yes, it is hard and I can totally do hard’ While thise seem to conflict (it ISN’T hard, or it IS hard), I guess you just choose whichever thought reaonates with you, is believable and helps you feel the desired emotion, right?
