The whole point is to become the best you. Search happiness and peace of mind in a body worth living in. There's a famous quote from I think from a trans man who said "transition doesn't bring me joy, it brings me peace of mind". That's kind of a motto I think is good to live by.
And perfection, its always good to aim high but to accept that none of us is ever perfect, that's not a human trait. And to realise how we're unique and transition is always unique and personal. What comes to passing, its good to not feel desperate because it works in a weird way and some times it works against all odds even. Pulling off a cis passable big buffed out gym amazon lady look is totally doable.

Height and size is not a problem, I'm a living example of that and I'm nowhere near tallest or biggest women out there. Some masculine traits are also fine when enough boxes tick to correct direction. Passing is almost like a checklist with people having a bit of variation on how much is needed for it to work. For most trans women, in the long run, passing becomes the least of issues. So much can be worked for making it work and HRT alone given the time can be so magical. As a goal I believe its a requirement for a normal and peaceful life. To each their own, but for me it was a high priority since beginning. Knowing how crazily diverse bunch of people pull it off is very encouraging.
One thing about this is the performative side of womanhood which can be so much fun to learn. Going crazy with all the endless options with clothing, makeup and everything "painted on" is so much fun and it can be quite a confidence boost too. I think its good to find ways to make transitioning a bit less of a pain and try to find the fun and positive in it. Easier said than done, but working towards cis passing has a lot of skill involved and that can be fun to dive into.
