3. Get an Exercise Program or Schedule.
Following a pre-set exercise program or schedule is important to give you direction and get the most out of exercising, and importantly, will stop you overtraining and burning out. Most weight training programs recommend that you focus on a body part every second day to allow for recovery of the muscle group. Having direction will ensure you keep coming back.
4. Reward Yourself when you Achieve Targets.
Rewarding yourself by buying something you need/want when you hit a certain weight loss target, or beat your personal best time for a given distance, will continue to inspire you to achieve, and will keep you focused on your goals.
5. Choose exercises you Enjoy.
On of the most important exercise tips I can give you is to choose exercises that you enjoy. If you get bored on a treadmill, get outdoors and see the sights as you jog. The same applies for exercise bikes, and getting out on the road. If you enjoy other peoples company, join an aerobics class. You could even do karate to get exercise while learning another skill. Do what you love and you will continue to do it.
