I think there is a difference between being able to see your flaws and seeing type as an explanation for some of them vs using type as an excuse.
Some people seem to think that if you recognize your flaws but don't overcome them overnight then you are just making excuses or not trying.
It can be hard to uproot certain flaws because they often don't exist separately from your whole person. They are often part of a whole package, and some of that package is pretty good. I often find a flaw is "applying" a strength to the wrong area.
I suppose the most frustrating thing I connect to my type is my time management and organization issues. I do see it as a flipside to certain strengths. I have the strengths of being flexible, imaginative, patient, and prioritizing my emotional well-being over tasks. These strengths may be misapplied at times. While I don't use that as an excuse, I also have found that accepting that my flaws not necessarily worse than the flaws in others actually helps improves them. Feeling guilty for running late or being messy tends to make it worse. Having compassion for myself instead of feeling like my brain is defective seems to enable better focus (perhaps accessing lesser preferred thinking styles without the mental block of defensiveness).
I don't think that being INFP means I am deeper, more empathetic, more insightful, more creative, more imaginative, etc.
A common INFP blindspot (and really, it must be said, INFJs have this too so I hate when it only gets pegged on us) is to feel they are too different from others, so that no one can understand them and no one may accept them for who they are. It's not special snowflake so much as feeling defective or outcast because you are sensitive to signals of value and aware of your emotional proximity to others. I think some of this does come from not being mirrored as children if your parents are not a similar type, and perhaps it even stems from actually being outcast in some way. Instead of using type as an excuse, it can be a relief to see why people respond to you as you do; you aren't inherently "bad" or "wrong". Hopefully once you are aware of the blindspot, you will use the awareness to avoid some of the problems it tends to cause for you.
For example, I apply my emotional sensitivity a lot less socially and am much less shy because of it. I don't personalize stuff that isn't personal as much; when you're a young INFP, every face can look like an emotional message to you, and it can be emotionally overwhelming, so that you may withdraw in a stubbornness to not be affected by others' valuations. Then you learn that their responses are often rather detached from what is going on; that grimace isn't directed towards you, but they have some stress in their personal life leaking out. Learning about type helped me realize how much my social anxiety was about a mix of emotional sensitivity and stubbornness to not be affected by others.
