All of my goals are well within my reach.

Reach implies stretching. Nothing within reach sits at chest height; you get it by standing on something, or by asking someone taller.

So this isn't saying the goal is close. It's saying the distance is crossable, which is different and more honest.

Name the stretch for one thing you want. The uncomfortable email, the money, the skill you'd have to be publicly bad at for a while. That's the chair you're standing on. Reaching without it is just looking up.
