It's a personal choice, and one could argue that it takes several years for the effects of HRT to make a difference in our appearance, and during that time our hair would be at a length we are happy with; we could save money for FFS or other bit of work if we need it, have laser and/or electrolysis, perfect our female voice, walk, mannerisms, and acclimate to blending in with other women by gradually going out as our true self, and then getting to the point that we are out everywhere except work, and then making somewhat of a seamless transition from part-time to full-time. Or, we can go full-time asap, and feel happier living authentically, but run a greater risk of being discriminated against, and possibly lose our job (you can still lose your job if you wait, but the difference is that in the first example you are in a more comfortable position), and it could be more difficult to find a new one during the awkward transition stages). I'm sure that immediate full-time transition works for some, but probably not for the vast majority of us; sometimes we're a lot better off delaying gratification, and doing what needs to be done, in order to achieve the best possible result.
