Adventures in Photoshop, Part __ ?

Trying to teach myself PS CC is sometimes fun and sometimes sends me screaming into the night. As in last night, trying to correct a photograph of a rose I wanted to have printed and just muffing it up horribly. *le sigh*

The various "sharpen" functions are ones I have not mastered yet at all.  I'm sure I'll love it when I master it but I'm at that stage I was when I transitioned from Photobucket to ipiccy a couple of years ago: "I just want to do this, I just want my little slider bar back, where is the eraser so I can selectively apply this effect?" etc etc etc.  That said I do LOVELOVEOVE the fun effects with fonts - especially drop shadows, contouring and glow effects.

This morning I had a little more luck inmproving contrast, brightness, color, warmth etc on a photo I took yesterday of flowers behind the garage, but it still feels like I'm in the "beginner's luck" stage. I didn't even attempt to sharpen either of these, btw. Baby steps, baby steps.....
