Pretty much, up to you. About the only thing I don't think you are likely to be able/allowed to do is get someone to do all the surgery, but not have any kind of hormone replacement, and I can't imagine anyone actually wanting to do that.
Options that exist:
1. Identify as correct gender to friends/family, let everyone else misgender you because you don't actually care that much.
2. Make some effort to pass.
3. Hormones.
4. Hormones plus at least some surgery. (e.g., some FTM will go for the top surgery so they look right, but not try to get the genitalia fixed because the technology is Not That Good.)
5. Hormones plus all the surgery.
In much of the world (I think?), you need hormones and possibly at least some surgery to get legal ID changed, but at least some places will change it more easily, and I believe some simply won't change it, period.
A couple of people have told me that transitioning is enough work and hassle that, if you can survive living without transitioning, it may be less stressful and painful to just look wrong, especially if your friends and family are supportive. But certainly, some people survive without the full surgery, or even without any surgery. Some because they don't think it's worth it, some because it's expensive and they aren't rich.
