1. Do you use fingertricks? If not, learn them
2. Solve slower, but don't pause in between. While solving one f2l pair, look for another (at the same time)
3. Practice a heck lot, do 50 solves a day or something
4. Lubricate your cube or get a better one
Those two tips should get you to 30 if you're dedicated.
edit: 2 more things added on, thanks skeletonboy
