LSAT rewards those who persevere, and what is life if not one long journey of perseverance. If you want it enough, then you will be able to do it. Temper your goals though, and go about it incrementally. Getting to your goal may takes months, if not years. Have the right mindset and expectations, and you will be able to go further. There is no shortcut, only heartfelt triumphs after profound struggling.
Personally, I have a 3.0 gpa, so to get into the top schools, I must get at least a 99 percentile lsat score. At some point you realize that improving is the easy part, and trying my best not to decline, now that gets depressing. To some degree, I think one has to become obsessed, or a hermit or a monk; harnessing motivation wherever you can and finding meaning in every little thing in life, good and bad, and devoting ungodly amounts of time to this seemingly marathon without end.
In another perspective, if you can get through this, you can just about get through anything. This is why the LSAT can be a good indicator and preparation for law school. Add oil!
