Capability increases the number of problems you can call manageable.

The line between a manageable problem and an overwhelming one moves as you become more capable. Nothing about the problems changes, only how many of them fall inside what you can handle, and that boundary keeps expanding as long as you keep learning. That expansion is one of the few things in life that reliably moves in your favour.

Notice what would have overwhelmed you three years ago and now would not. Then pick something currently just outside the line and work toward it deliberately.
