Perceived effort.
One thing I realized on today's training commute ride was that perceived effort is one great reason to get a heart rate monitor. For me, it's always LOWER than my actual effort.
For instance, I was trying to hold a steady tempo at 85% MHR (160-170 bpm), letting up only for lights. At some points, I went over this and started reaching 170+ bpm. However, I didn't feel it while I was riding; I actually felt perfectly fine. This may be the reason why I was burning out on rides and didn't know why; I would have little control over my heart rate. When I stood within my range, I still had enough left in me to go a little harder when I needed to and NOT be completely spent.
The only way I would have known that is by having my HRM.
Just sayin'.

I generally have the opposite problem - I have a hard time keeping my heart rate up. As you learn how your body behaves, you will start to get a sense of RPE and heart rate and how yours likes to work. I can pretty much nail 160 and 170 beats a minute spot on with RPE. With power, it's even easier. 85% is a good start at SST.

Do get a HRM.
I think you'll learn over time why the criticism of HR is valid - it frequently de-couples from perceived effort, especially if you're fatigued, dehydrated, short on sleep, or a variety of other reasons.
For example, yesterday I went out to do 2x20, using my HR as threshold guide. But as soon as I got on the bike I knew I hadn't fully recovered from the weekend rides. My legs told me, and my HR confirmed it when I couldn't get it up into the target range. So I just rolled around for a while... and later my legs started feeling better and I was able to knock out some efforts, bu tmy pulse never did come up into target range.
Anyway, you'll learn a lot by watching HR.

The decoupling is actually very telling of your aerobic base. In WKO+ there's actually a statistic for it, Pa:HR. I have the same issue as OP for the first part of an interval. It feels easy so I overreach. But at the end...
