Anyone here in investment sales?

As the title says:

I just wanted to get an opinion on what the industry looks like.

So far, I understand that the initial stage is a grind, and you have to build your book of business. However, I’ve seen more discouraging comments than encouraging ones, and I can’t verify whether they come from experience or just external observation.

Therefore, I’d like to hear from someone who has been there and done that.
