Could My Goal Be At My Fingertips??

As my track season and WISE project will soon becoming to a close, could I possibly reach my goal of breaking 50 secs? Only the next three weeks will tell. My fastest time so far is 52.4. I've been thinking that if I don't run in the 100 meter dash and 4by1 semi-finals, I will have more energy to use in the 400, thus for getting a faster time. I want to try this at my next meet which is this Thursday.

I need to train hard these next few weeks so my chance of breaking 50 goes up. With enough hard work, determination, and a positive mindset, I believe that reaching my goal will in fact be at my fingertips. IT WOULD BE THE BEST FEELING IN THE WORLD!
