Keep It Simple

In your training and desire to 'overcome the boredom' you will probably look into many new, different and 'exciting' training methods. You will look at new ways to use your techniques. With Kung Fu many always look for fancy applications because they think 'it's cool'. My answer to this is to "Keep It Simple"! When you start to get fancy before you have the most basic techniques you will get sloppy and make all of your technique suffer.
In a more clear way: You are doing squats to improve your legs strength. You get bored. You see someone doing a 'fancy' version of a squat (jump squats, clean and press, etc). You decide to try one. Since you are new to lifting you haven't developed the necessary skills, strength (core, legs) and coordination to do the exercise. You seriously injure yourself.
With Kung Fu this can happen also. There have been many times when I have had to hold a student from doing 'tornado' kicks (360 rotation) because they aren't ready for any number of reasons. Or you see a student trying to apply a sparring technique that is beyond their skill level. They get hit very cleanly because they can't perform a basic block yet!
In conclusion, when you are training, whether it be in Kung Fu or just regular fitness, stay with our general princicple of not being in a hurry to get there and do the technique or exercise level that you are truly ready for. Keep it simple until you can handle it. If you aren't sure how to judge, find someone qualified who can!
