I voted yes, because it does say "if you think it's best" lol. And that's really what matters in the end. I've been TT a lot the past few weeks, because I know it's summer and work starts in the fall, so I'll only have time for dailies then.
Pros: you get things done faster! For me the biggest pro is getting rid of that "ugh, hideousness anxiety" I get when I have to wait. It diminishes some of the impatience.
Cons: you might find (if you TT constantly) that you get things too quickly. I now have a "stable" house and enough money to upgrade whatever the heck I want. This might not be a con though, if you're constantly creative/changing your town. Another con is that you might find that you have TOO much to do. I mean, you can basically do as many days as you want, all full of checking shops, TTing villagers, getting pings for PWPs, landscaping, etc. Burnout can occur!
So it seems there's more cons than pros. But I still say go for it if it's the best for you, just space things out a bit. It is 100% worth it for me, since I am almost at a stage where I can do dailies while slowly developing my town and houses!
