Question

Does this sentence make sense?

I believe that it would be a truly burdensome decision to make. In most cases, you should follow what your heart has to say.
(Mainly the burdensome part, does it fit?)

Answer 1

i think the first sentence is good. But the second sentence is a bit awkward. maybe you could say something like "In most cases, you should listen to and act on what your heart says."

Answer 2

I agree that the first sentence is good. The second one can use some simplicity.
"In most cases, you should listen to your heart."

Answer 3

I think it makes sense...the first sentence says that yes there are decisions which are made but are burdensome. However, mostly you should follow your heart.
