How to get there?

In creating a system, we usually follow a model. A SDLC model to be exact. Both predictive and adaptive approaches use this model. And if I were to construct my own SDLC model, it would go like this:

PLANNING & ANALYSIS

It would all start with plans. What I want, how would I achieve it and what are the approaches I would use to get to the top. And these plans would need careful and thorough analysis.

TESTING & IMPLEMENTATION

After the creation of plans and analysis is the testing and implementation. In this phase, everything that has been planned shall be implemented and tested, to enact the things I've decided to carry out.

EVALUATION

After it has been tested and implemented, one should analyze the effectiveness of the plans and course of actions that has been done. In this phase, the results should be examined.

MAINTAIN & IMPROVE

This would be the last phase of my model. It is where I would maintain the things and plans that are effective and efficient in achieving my objectives in life. And to improve those that fail.

If I were to choose what approach I'd use.
Predictive or Adaptive?
I think I'd prefer the adaptive approach.
Yes, planning is a great factor in achieving one's objectives in life but
as I've mature, I've realized that everything doesn't always go with one's plan.
There will always be unexpected circumstances thus one needs to adapt with whatever life has brought.
Changes, that's what we call it. The only constant thing I guess.
It ain't being pessimistic, it's about being practical.
"Go with the flow." Align your next move in the current situation. But do not lose sight of what you aim to achieve. Adapt. But it is wiser to predict and adapt. So I guess the integration of both Predictive and Adaptive approaches would be best used.
