If you mean a "youthful" style, there's lots of pieces like that. Try almost any Mozart or Haydn sonata, some Czerny pieces (Variations on a theme by Rhode ["La Ricordanza"]), also the third movement of Chopin's piano concerto in E (no. 1). You'd be suprized that Rachmaninoff has some youthful pieces too - op. 39 no. 4 (b minor). Chopin's Butterfly etude is another wone (G-flat Major). Is this what you are looking for?
