Taking pleasure in things leads to enjoyment. On of my own personal goals is to be in a constant state of enjoyment. From a practical perspective pleasure can be subjective to a degree (although for the majority there is general consistency about what leads to enjoyment).
This does not mean opportunities for enjoyment are constantly available to everyone, it just might vary.
The Bottom Line
The practice of enjoyment, taking pleasure in things, is a choice. Simply put, you can control whether you are in a state of enjoyment. It is afterall about perspective and if you perceive life occurrences in a particular way, arguably every thing could have a pleasurable aspect.
Life is a series of pleasurable events, if you want it to be. Why not? The fact that stress and distress can worm its way into our daily routines is always puzzling to me.
Maximizing Pleasure
That is not to say every life event provides the same level of pleasure and working towards a goal of maximizing your personal pleasure (not at the expense of others, of course) is both an admirable and obtainable goal.
To some extent it requires conscious control of your emotional well being. The positive or pleasurable aspects of a thing sometimes require some effort to achieve, but I would argue, regardless of what you are up against, some form of enjoyment opportunity exists.
You just need to both recognize and embrace it.
