But How??

I want to spend my precious holiday usefully and wisely but how?? I want to make use of every single minute of my holiday but how?? Someone advised me to spend my holiday usefully so that I would not regret like how the "someone" did.

Things in my mind:
- Read more books
- Learn new things
- Be prepared for Form 4
- Improve my piano techniques, i.e. scales and pieces
- I still wanna grow taller..T.T
- More shows and movies!!
- Enjoy my holiday and not regret for not spending my holiday usefully..

I'm actually wasting my time typing this..argh. I NEED TO ACHIEVE MY GOALS!!!
