Depends on whether you're up for it or not, Anne.
There will be some drawbacks completing it in half the time - be prepared to work like a sunovabish and stress, let's not forget the stress.

....but, wouldn't it be thrilling, constantly learning new things? and at the end of it all, wouldn't it be fulfilling?

If yes, do it.

If no, don't do it.

it's your take on it, Anne.
