Is it too late to start S10 and complete the Season Journey?

Hey guys. I've never really played a season before, only normal mode. I have a level 70 wizard that was powerleveled in it, and I know how to gear my player for the harder journey requirements like GR75, which I can do on normal mode pretty easily. Do you think it's worth it to do the journey before the season ends? I'm definitely going to play a lot S11, I just didn't know if it's too late to start S10; to at least get the extra stash tab and stuff. I just don't know how soon it'll end. Thanks.
