Answer:
The answer to this question definitely depends on your own views on what motivates you to become active and perform some sort of sport, or do exercise. However, there are some options here that would definitely play a key role not just on whether or not you perform exercise, but also whether you will last in it, and if you will engage in one form, or another.
1. Your fitness level, would be a motivator only if you wish to change it. For example, if you are overweight, but you fill fine with it, and you do not have any lasting complications from it, you might find exercise unnecessary.
2. Your mindset: definitely. How you see yourself, and how you feel about exercise, as well as what you wish to accomplish, will become some of the most powerful motivators to start exercizing, staying in it, and lasting.
3. Setting reasonable goals: This is a MUST. If you are starting on the road of exercise, and you set up standards that are too high, if you do not meet them, you will feel less inclined towards this activity.
4. The time of day you exercise. Definitely. Some people are better at working out during the daytime, and some at night time. Your style and needs will motivate you. Also, if you work all day, and have to go to the gym at night, you might be less motivated due to exhaustion.
To me, age and viewing exercise as a lifelong process are not necessarily motivators, unless you see them as negative.
