Should I just give up?

I've taken the LSAT 3 times and I've done horribly.

1st LSAT- 147 (fresh out of college)

2nd LSAT- 153 (1 year out of college)

3rd LSAT (this past Sept)- 144. (3 years out of college)

the sad part is I actually studied for the Sept. one and it's the worse score I've gotten. I'm starting to think maybe law school is just not for me....Should I give it one last try?!????
