Is this bad?

[ProfPhoenix]

So I work on the personality on my 45 min walk to school and I was curious as if that's as good as sitting down and forcing.

Any work you put in helps. No time spent on your tulpa is wasted time. Spending time solely focused on your tulpa, and not worrying about traffic or walking into things might be better, but talking to your tulpa while doing other things can't hurt.

 

When in doubt, force more.

That's called passive forcing and it's just as valid as any other kind of forcing. As Yuki said, any time spent with your tulpa is good time.
