My bad news to the younger members of this forum : no it doesn't get better.
My good news to the younger members of the forum: It can get better. I know this from my own experience.
Note that I said "can," not "will." Nothing is guaranteed. Progress is certainly not a function of age. Progress depends on a variety of things -- motivation, engagement, persistence, faith, courage, willingness to tolerate distress, facing problems rather than avoiding, taking responsibility vs. blaming, trying to expand your understanding, thinking for yourself, willingness to take risks, etc.
