Long ENFP response
Is there a balance between accepting one's self as you already are but still setting a course to change who you are? Are these two aims contradictory or reconcilable?
I don't think the two are contradictory at all and actually go hand in hand. I think well-balanced people with a clear view of themselves and others will be aware of their shortcomings and strengths and have a healthy ego response to each. Meaning you don't beat yourself up on the shortcoming and you don't become an egomaniac with the strengths. You're able to objectively see how you 'rank' with others in life.
I also think balanced people know they will change over time and accept it. Further balanced people know they have the right to empower themselves and control their destinies.
Basically, they are not mutually exclusive. Just because you acknowledge and accept yourself as you are in this moment doesn't mean you have to lock yourself in a prison and stubbornly try to stay exactly the way you are. And just because you want to change something, doesn't mean you hate yourself.
Instead, I think the two things you mentioned are complementary and in fact necessary to going about self-improvement in a healthy and effective way.
Balanced healthy people can accept responsibility and try to make things right when they can and acce
What practical techniques could a person employ to strike this balance?
1) Ask yourself why do you want to change? What is your motivation? Is it do avoid something or to run to something? Do you really think you can change? Do you have the resolve and the tools necessary?
2) Perhaps before asking this, taking an honest assessment of yourself is helpful. Enlisting your friends and even strangers (a therapist? counselor? advisor?) to see how they view you and your strengths and weaknesses. There is no value judgement on these things, they are what they are.
3) How bad is the bad really? There are points in our lives where we just have to admit it's too late for things and that we cannot change the past or other people. Or just accept the truth of the moment. From my own experience there are lots of things I used to be ashamed or angry or hurt about. And there was just no relief in sight.
A practical step towards that is making an assessment of pain points in your life, things you deny or avoid or carry a sense of failure or regret or anger about. And then write down why you feel that way, who did you fail, who do you blame, what were the consequences, can you remedy the situation now? What can you do to change that situation? What resolution would make you happy? What do you really want?
4) Visualization and assessment in general. I think from your 'short questionnaire' post you're on the right track.
5) Thank yourself. Honor yourself. Be kind to yourself. Our worst critics are usually our own selves. We would never say or treat our friends the way we do ourselves.
6) When something "bad" happens, instead of yelling at yourself, avoiding the problem, or blaming others, be smart about it. Figure out what went wrong and why and how you can prevent it in the future. Acknowledge how much impact the mistake or slip-up actually has, honor your anger or disappointment, and be responsible towards anyone else negatively impacted by it. "Fix it" if you can. Then use all this as a motivator to do better and move on.
6b) To strike a balance you really need to start with honest assessment and always be humanitarian. Remember, you're changing because (as cheesy as this sounds) you are
worth it and people around you are worth it. I think integrating that respect for self and others goes a loooong way to striking that balance or moreover, just being effective at achieving personal growth and happiness.
Hope this helps and good luck with all this! I think this response started veering away from the OP but you get the gist of it.

And yeah, I know I sound like a motherflippin' metaphysical new age hippie. :rolli:
