There is nothing like the present time. Later can turn from days to months, to even years. I myself have been in a progressive state of not working much toward my own journey, other than my own wardrobe.
It all depends on how much work you put into the situation, or if anything may be holding you back to start. I know my journey is long and will remain long due to currently still actively being in the U.S. Army Reserve, so I can, but can't, start therapy to start myself to a better life on my own. But in the meantime, I can still work on my own perspective of self betterment through living as myself, though only being at the first step still. Within time I will eventually take my second, and third step, and so on, but as I say my journey is still in progress.
Though only you, yourself can make your own decision to start now or later.
